Helping people with computers... one answer at a time.

Once you've been assigned a static IP address you'll need to configure the network-connected device manually to use it. We'll look at how.

I have a server and have been assigned a static IP by my ISP. How do I go about configuring my server to work on its assigned IP?

99% of Windows internet users use what are called "dynamic" IP addresses. That means each time you connect to the internet, your ISP assigns you an IP address to use when you connect. The next time you connect, you might get a different address. If you're only connecting out to the internet, that's all you need.

If you expect people to connect in, say you want to run a web server that you want people to be able to find and visit, you'll most likely need a static IP address. A static IP is assigned by your ISP to you permanently, and identifies your server to the world.

The question is: once the IP is assigned ... then what?

If your computer is connected directly to the internet, meaning it's not behind a router or a firewall, it's actually pretty simple. In Control Panel, Network Connections, find the network connection that represents your connection to the internet. Most often it's labeled simply Local Area Connection. Right click on that and select Properties. Now click on the Internet Protocol (TCP/IP) item in the list (you may have to scroll down within the list to find it):

Local Area Connection Properties

Now click on the properties button.

A default configuration will have both Obtain an IP address automatically, and Obtain DNS server address automatically selected.

Internet Protocol Properties

Click on Use the following IP address: and enter the IP address, subnet mask, and default gateway information that your ISP should have given you. (If they did not give you all three, ask them.)

In most cases they will also give you IP addresses for the DNS servers you should use. Click on Use the following DNS server addresses and enter that information as well.

That's it. Once you "OK" your way out of those configuration dialogs, your computer should now respond to its assigned IP address.

"The question is: once the IP is assigned ... then what?"

If you're behind a router, things get a little more complicated.

The first thing to realize is that the static IP address should probably be assigned to the router. That will require configuring the router, much like we configured your server above. Exactly how will vary from router to router, but the principals are the same: you'll configure the router to not get an IP address dynamically, but instead you'll enter the IP, gateway, subnet, and possibly DNS information by hand, using whatever approach your router uses for configuration.

The "trick", if you want to call it that, is telling the router to pass on requests it receives from the internet to your server. It's typically referred to as port-forwarding. Once again, depending on how your router is configured, the general idea is that you configure it to accept requests on certain "ports" and direct them to certain computers on your LAN.

The port part is fairly easy. If you want to set up a web server, then you'll know that port 80, where http requests are handled, is the port you want to forward. But to where?

Much like your direct connection to the internet, you'll need to assign your server a static IP address within your local network, so that the router knows what machine to forward the requests to. Typically a router will tell you, or let you configure, the range of IP addresses it will assign from dynamically, so you'll simply want to choose an IP address outside of that range. For example my router at home is configured to assign dynamic IPs starting at and up. So I've elected to assign a static IP on my local area network of ( is the address of the router on the local network).

So the rest is simply a variation on what I've already covered: configure that server with the static IP you've chosen, a subnet mask of should do, the default gateway should be the router ( in my case), and quite probably the router should also be your DNS. If not, use the DNS settings that your ISP assigned you.

Now configure the router to forward port 80 traffic to the static IP address you chose, and ... there you are. Your web server, behind a router, should be visible from the internet.

Port forwarding is actually very powerful, when set up correctly. In my case, I have port 80 traffic, for a web server, directed at one machine, Remote Desktop traffic (port 3389) is directed at another, and Skype (a post Skype selects randomly at setup time) to yet another.

When assigning a static IP address to a server on your LAN, behind a router, there is more to it than simply chosing an IP address outside of the DHCP range given out by the router. It also should be within the same subnet so that other computers on your LAN can see the server. Subnetting is a whole 'nother subject, but in the example given, had the server been assigned or it would not have worked. That is, the static IP has to begin with 192.168.1 (in this particular case due to the subnet mask).

I have a wireless router, and it does not allow other users to connect to my computer e.g. say i have a gaming server up. no one out of my network can connect to my server, how do i foward my ip or allow other clients to join my computer

August 18, 2005 4:38 PM

You need to open up the ports that the gaming server needs on your router, and indicate which of your machines that traffic should go to. It's called "port forwarding" in most cases.

I can't be too much more specific than that because the ports needed will vary based on your game, and how you set it up will vary based on your router. But hopefully documentation for both will allow you to get there from here.

I have a wireless LAN and I am fond of playing multiplayer games online. The thing is whenever I play them, I get disconnected from the game server that I connect to and also get disconnected from the wireless network (yes, that means no internet unless I go to disable the network connection and re-enable it again). Now, I've read that in order for games to work, I needed to configure their specific game ports. And so I did but I still keep disconnected. I have dynamic IP addresses and when I configrured the game ports, I only listed the first two out of the four possible IP addresses I can obtain(note that it's dynamic). Is there anything that I missed? Thanks for the help.

September 15, 2005 8:23 AM

I set up my router using a static IP address from my ISP. My PC works fine when I set up the dailup connection properly, but is there a way to set up a wireless laptop? Once I change the router to static IP I can't connect through to the internet with the wirless laptop. I see the network and everything else is fine...Can you help? THANKS

September 15, 2005 4:33 PM

Well, it's hard to say because I don't have a clear picture of what you've set up.

Your router should be using a static IP from your ISP on the WAN connection. But you want your computers to use dynamic IPs, which would be provided by the router. Make sure that the router has DHCP enabled for the LAN side. That's actually exactly how I operate here at home.

September 16, 2005 9:12 PM

Hi Leo,

I am preparing for my CCNA certification. I purchased used Cisco routers and switches for my home lab to practice on. I did set up my home lab network and configured all the interfaces with private IP addresses, which I randomly picked, and also configured them with routing protocols (rip and igrp).

The configuration is fine within my network (between my Cisco routers and switches), and they are exchanging information. However, I could not make them talk to my internet connected computers.

I have two computers, which are connected to internet using Linksys VoIP broadband router and cable modem configured using DHCP/auto IP.

The Linksys router has 3 ports for connecting to computers and 2 ports for telephone line. This router also assigns up to 50 private DHCP IP addresses. I am trying to use these new IP addresses to reconfigure my home lab network routers and switches interfaces.

How should I approach it so that I can reconfigure my lab network interfaces with the new IP addresses and also establish communication between my lab network and computers?

Any help or suggestions you can offer is greatly appreciated.

So I am not able to retrieve Ipconfiguration..
Please Help me in this regard.

Josil: "media state disconnected" means that the cable is unplugged or the wireless has no connection. ipconfig shows information for an active conneciton.

I currently have a wireless lan at home with my sister's computer being connected to the wireless adsl router via her computer's ethernet port and my computer connected via its wireless card. She used to get the error message "Shareaza may experience poor download performance as you are behind a nat router or firewall". According to the shareaza help site I configured zonealarm pro, set up a static ip address on her comp and enabled port forwarding on her router so Shareaza ( a p2p application like kazaa) could function properly which it did. Though the internet works fine on my computer i get the same message she used to get so again i configured zone alarm pro and made my ip address a static would i do port forwarding since my comp isnt connected directly to a router? or dont i have to do port forwarding to fix this error? or is port forwadding not possible on a computer which has a wireless thernet card?

September 26, 2005 8:43 AM

Port forwarding happens on a router. If there's no router, there's no forwarding required. If you are sharing the router, a forwarded port can go to only one computer.

Hi Leo,
I bought a netgear wireless router with 4 port switch, I have sprint dsl and I know I have static Ip, but either I have really bad luck or my dsl modem is odd, because I can't ever get into the router settings to change it to static ip, I've tried linksys aswell with the same if not worse results, any suggestions otherwise I'm just gonna gice up, I don't know what else to do!

Dear Leo,
I have a question, i have an ADSL service with a dlink 310 modem(lan-Router). the isp gave me a username and password, i used it to connect, but at the same time i could connect to my isp using ip configuration without need to log on, i uses as my computers ip, and as server ip, for dns server, no i changed my service to 512k, but my aacount with username and password has only 5GB each month, i can not connect to internet using IP configuration, if i could do that like before, so i could download more than 5 GB, what can i do? why i can not connect with ip anymore? how can i detect the ip adresse that i can put in lan settings?
Sincererly yours,

Dear Mr.Leo,
I am beginner in Networking and I was going through your wonderful article
Will you able to clarify a doubt from my side?

I have an internet leased line with static IP's given by ISP
I am using DLink router and the static IP and DNS information given by the ISP is entered in the WAN section.
The private IP of router is and I have a windows 2000 server in my LAN with the private IP and I want to use the server as a webserver.
Please advice me how can I assign a static IP which is in the range 213.X.X.X to my windows 2000 server and how can i set it as a webserver so that it can be accessed from outside the LAN

Thanks & Regards

I was phished and my email was being read by someone I don't know. I tried to change my ip by doing the following step above, but my computer will not change it. I went to start, run, cmd, ipconfig/release, then to tcp/icp and then added my own ip address. closed the box and then went back in and then let to computer to assign ip automatically. I went back into cmd, release all and sure enough my ip was still the same. Any suggestions? I am connected to an at&t modem.

Your IP address probably has nothing to do with your being phished or your
email being read.

Your IP address is *assigned* to you, you don't pick it or force it to change.
But like I said, that probably has little to do with the situation you're in.

I followed your guide and have had everything working for a number of months now, THANKS!!

Now I have a new issue. My PC has 3 network adapters (2 wired and 1 wireless). I only use 1 wired and the wireless. The wired connection is the one I setup to have a static IP of Now, I am needing to set my wireless to also have a static IP address. I followed the steps above once again, but it won't let me do it. I am getting a message that says, "Warning - Multiple default gateways are intended to provide redundancy to a single network (such as intranet or the Internet). They will not function properly when the gateways are on 2 seperate disjoint networks (such as one on your intranet and one on the Internet). Do you want to save this configuration?"

If I choose yes, it proceeds, but will not properly connect saying something about "Unidentified network".

What do I do?

For those of you looking for your static info, gateway, etc, open a command window (start| Run| CMD|
Type "ipconfig" in the new window. There's your info.

This may not work in all situations. YMMV, as always.

Hey Leo.
Im currently running a Speedstream router ADSL2+ directly into a Netgear wireless router and broadcasting to my laptop. I don't have any desktops connected to the routers. I was wondering how i could get my laptop to host games on Warcraft using port 6112. I've tried numerous guides about setting up Static IP's so that i can portforward from my speedstream, and I've tried assigning static ip's on my netgear and portforwarding from there, but nothing seems to work. Can you help me out here?
Much Appreciated

I am having issue with my static IP address. I followed your instructions and was able to connect to the internet. I am using Windows XP. However, it seems that every other day my computer resets the IP protocol to "obtain an IP address automatically" and I have to manually input the static IP address along with all the other subnet mask and default gateway addresses. I can't figure out anyway to get it to stop. Every other day like clockwork it simply resets itself and I have to reconfigure the address. Any ideas?


July 9, 2008 2:42 PM

Hi all!
I have an static IP adress and my conection works fine, until after some hours, 4, 8 or what ever it loses connectivity.
Every thing seems to be OK and suddenly there is no connectivity.
I think is something with my ISP DNS to do, because when I set the ipconfig/registerdns command, it works igen for a while, but it seems not to be the best solution.
What I have to do is unplug the modem (reset under a couple minutes) plug again and it works again, until the next 3,4 hours.
What can it be? TTL that does not map my ip or what?
I called my ISP, but they couldnīt solve the problem...
Any ideas?

July 9, 2008 8:16 PM

Hi Leo,

I have some questions about installing a second server in a network, the existing one is SBS 2003 and is the file server/emails/DC/basically everything in one.

I'm wanting to add a second server running 2003 server standard and wondering if its possible to do all that you mentioned in this article including assigning a static ip address (do i have to get another static ip address assigned to my 2nd server??)?

You mentioned that you had your port forward different programs to different pc's and just wondering if i can use this type of system?

It is also because i want to create a new domain for this server and its users, and if possible i would restrict both servers from being able to communicate from each other.

Any help with this would be very much appreciated

October 14, 2008 8:19 PM

Hi Leo,
The article is simple and easy to follow.
I have couple of questions:
1. What if there have to be two web servers behind the router?
2. is port forwarding any way connected to NAT concept?

Thanks In advance,

1) it can be done, but only one web server can be on port 80, the other must be on some other port. That means configuring the router to forward that other port, configuring the server to listen on that other port, and users to access the web site explicitly specifying that other port (as in

2) It's part of the NAT concept. One one site you have local IP address, and on the other you have a public IP. You're translating IP addresses for all packets that cross through the router, regardless of direction.

If you guys have a dynamic ip address and want to host a server...

Check out this site allows you to create a few names for free. If you download thier client it will update your address to the domain name.

I host 2 domains using 1and1, and use DynDNS to tell everone my new address.

My Dynamic DNS name is

then I create cnames using 1and1 to point to that DNS.

I am trying to set up a win2003 server thru which computers will connect to the internet. The server has two NICs, one for DHCP and the other to connect to the internet. Access to the internet is currently thru a Motorola DSL using one static ip address; the DSL is also a dhcp server (I want to turn off the dhcp server on the dsland use the server to assign the ip addresses). Our Qwest ISP informed me that our static ip address does not have a subnet mask but they gave us primary and secondary dns's. How do I configure the server so it route internet and dhcp serves to my computers in my office?

In my medical office we have no server. We have a VoIP phone system which provides us a T1 dedicated line out to the Internet. We also have an EMR system that we use for patient records. We chose to have the vendor of the software house the server on their end since we have no internal IT dept. So the vendor provided a Juniper router to allow our computers to connect to the software. Now the ISP for our VoIP has sent out a letter saying that they are giving us a new static IP address and that we need to make those changes. I will pass the letter along to the software vendor to make those changes to the router the provide for us, but do I follow the steps in the article above to make the changes to the all the office computers?

I'm guessing not, but it really depends on how that router was set up. You'll need to check with that vendor.

I read the article but I need to know what the settings for a Static IP for a DSL Modem and a Router? When all is configured correctly can my computer find the internet connected to the DSL modem? Or a Router port or both? I guess what I am really asking is should the Modem settings be "BRIDGED" and NO IP address? I am getting conflicting reports.

Most commonly you don't need static IP addresses or bridge mode. Leave the router in it's default configuration of "get IP address automatically" for the internet connection, and "DHCP enabled" for the local area connection. The router will get the internet IP address automatically, and then assign dyanmic IP addresses to local machines.

I need your help and advise, Firstly, I call my ISP provider in order to get static IP address so they told I have to pay extra fee every month. Secondly, is there anyway I can get static IP address for fee?

I would be very happy if you could help me please,

It's totally up to the ISP - if they charge for it (most do since it is extra work for them), then there's no way to get it without paying.

Probably not, but you'll have to check with your ISP.
September 1, 2009 4:50 PM

Yes, is there any static ip adresses i can just type in ?

Nope. It must be assigned by your ISP (for direct internet connections) or you must carefully configure your local network to support it. It's not just something you type in.

Hi,Im in the UK and broadband wont give me a static IP addy for my "home" use,only bloody business !! But I have to have one for CCTV,any ideas how I can do this?..Im using wireless and vista.Thanks

November 12, 2009 5:57 PM

Here's a brief rundown on getting a static IP:

Most ISPs know that a static IP is far more useful than a dynamic IP for setting up remote login, web servers, mail servers, CCTV systems, etc.

Accordingly, they sell inexpensive consumer plans with dynamic IPs, and expensive business plans with Static IPs.

There is no way to 'convert' your dynamic IP to a static IP, since the IP is provided by your ISP.

BUT - there is a way to link your home computer to a service called dyndns, which gives you a web address that connects to their software on your computer, updating the IP address as your ISP changes it.

This is what I use to remote into my mac with my iphone from work, and it works like a charm.

I currently have the new Sprint Mifi, but purchased a static ip address for the routher. Now I am having problems knowing what to do-should I disable DHCP? If says if I disable it, I need to set up a gateway through my computer. Is it easier just to port forward? A lot of my posts and stuff get lost with a dynamic IP-please help!

Sir, my brother just fixed our internet a year ago... he used an

IP Address:
Subnet: 255, 255, 255, 0
Default Gateway:

I changed it, without knowing that I can't revert it back.

when I try to revert it back, it tells me that the static IP is being used, that I should choose another one, what should I do to gain back that IP address?

So if you dont have a router you dont need a static ip address?

Whether or not you have a router has nothing to do with it, really. Some situations require static IPs, but most people rarely need them.

February 26, 2010 7:50 AM

@"Some situations require static IPs, but most people rarely need them."
Obviously you have not heard of ADSL, everyone using ADSL requires a router

Which has nothing to do with whether or not static IPs are required.

Hello Sir,
I have a static ip address that i need to access from the internet. I'm able to access it by giving the ip address the only problem is I want to associate a dns to this ip. eg ; when I give the ip address I'm able to ping it from other machines but when I give the associated dns entry like or I'm not able to ping.

192.168.x.x addresses are addresses on your local network and cannot be routed to or connected directly over the internet or DNS.

Is it possible to use a Static IP at two different places? For example, if I set up a Static IP at my mother's house, I take my laptop to my father's, and I can not use my wireless connection, or I have to go back to a Dynamic IP.

I need help with a small office network config.

My ISP is setting up a static IP address to use for my office rather a dynamic setup. My chain is Cable Modem>Router>HUB/Switch>to all computers and network printers.

I do not have a server just the the 3 items i mentioned before.

hmn, re: manually configuring static IP. IP Address has been entered in the TCP/IP Properties "Use following IP Addresses" and DNS fields, as described, os windows xp svc pk 3. When i test the connection it fails with "no PPP configuration" error. Sir, may i ask, is it required to append/register DNS suffixes in advanced settings? do the DNS and IP have to be assigned by the dialup ISP or is it possible to use the Server address and Client IP located in the Status Details tab at the time of connection? thank you for your help.

I then setup the network card as you explain and it seems to be working but when I ask iis to start the website which has the binding to my default gateway ip that is listed in the drop down and set the port to 80 I get a The format of the specified network name is invalid
Any Ideas

December 19, 2010 6:07 AM

My home network includes a combination router and DHCP server. For remote accessibility purposes, I'd like to assign static IP addresses to some of my computers...but I want to make sure that these same devices are using the most efficient and up-to-date DNS servers--the addresses for which are dynamically provided to my router via my ISP.

When a computer is configured to use a static IP address, the DNS server addresses must be manually assigned. Why can't my computer have static IP addresses but dynamic DNS servers?

How does everyone else handle this? Do you occasionally check to see if your DNS servers have been updated....and then update your computers accordingly?

I've yet to see this question addressed in any articles that describe how to configure static IP addresses.

Typically, yes, if you configure static IP addresses you also take on the role of configuring the proper DNS servers. I don't see a huge advantage in trying to keep the on the so-called 'latest and greatst'. You can try setting them to the IP address of your router, as some routers will act as a DNS gateway.

I am connecting to an integrated voice/data T1 circuit from at&t. They are providing a router that breaks out voice channels to my Avaya phone system and a cat5e for internet access. Do I connect the data cable to my firewall or do I connect it to a port on my switch? If it's firewall, do I need to configure anything on my firewall? we have a similar setup using a different provider but it was set up before I was with this company. thanks.

January 30, 2011 11:33 AM

@Small Fish, dude, basing on experience, you are the one to set up the LAN side, so you will be the one to decide if you want to connect a firewall or a switch or an internal router behind the one provided and managed by at&t. i know for a fact that you should connect @ the fast/gigethernet 0/0 for data connection, and it is usually not turn up yet, so you need to call the ones managing your service and ask them to turn it up/admin up it for you, ask as well for the useable ip addresses, default gateway and DNS servers, for you to set your LAN. Thanks and hope this helps.

May 4, 2011 9:46 AM

What if I have two web servers on the same router. Will they share port 80 and the traffic will know which machine to goto by the external IP address? Or do I need to change the http port on one of the servers? If so how?

A static ip address is something you would have to order from your ISP. Ask Leo has no way of doing this for you.

I really need some help accessing a webcam at home from another network. Is this "camstreams" and where do ports 80 or 8080 fit in? I don't think I'm alone in this struggle. I've tried both an Edimax and EasyN FS wireless weans. Both manufacturers have very poor installation manuals and quirky software. Thanks Bobby

Thank you for the explanation. While the actual act of setting IPs is easy to find out, many tutorials fail to answer the question - 'why?' Yours is the first explanation that adequately answered this question for me

I get all this, the final question I have is setting up the router when I have a registered domain being hosted (by maybe). Do I uses GODADDY's DNS servers, or the ISP's DNS servers?

June 20, 2012 2:33 PM

Those two things are unrelated... You domain's IP and your home Internet IP. For your home router you set it up following you ISPs instructions. And don't try to use your domain's IP address on your router. Unless you don't want an Internet connection, that is!
