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

Determining your own IP address is very easy, but it first requires understanding which IP address it is you want to see.

How to find the IP address of my computer? Is there any command?

Sure there are commands.

But I have to ask you a question first:

Which IP address do you want?

Your Computer

Each machine connected to a TCP/IP network is assigned an IP address; this we already know. It's not that difficult to determine what that IP address is.

In versions of Windows from Windows 2000 and later, run the Windows Command Prompt (Typically in Start, All Programs, Accessories). In the command prompt, type IPCONFIG and you'll get something similar to this:

Windows IP Configuration

Ethernet adapter Local Area Connection 2:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.1.5
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1
"... since I'm behind a router, this is not the IP address that will actually be used when I access the internet."

As you can see, the IP address of this computer is listed as "192.168.1.5".

(In Windows 98 and 95, you can Start->Run a program called "winipcfg" and get roughly the same information without using a command prompt.)

Now it's important to note that this is the IP address of the computer. In fact, since I'm behind a router, this is not the IP address that will actually be used when I access the internet. The IP address shown here is my computer's IP address on my local network only.

Your Internet IP Address

The IP address assigned to your internet connection is most easily seen by visiting any of the many "show me my IP address" pages on the internet. The one I remember most often is ipchicken.com, but there are others.

Including my own: http://ask-leo.com/whats_my_ip_address.html will show you your internet IP address and a few additional bits of information.

Even better, since any web site you visit gets the information, your IP address is: 54.161.202.106.

Why are they different?

Sometimes they're not. If your computer is connected directly to the internet, then your machine is assigned an internet IP address. The IP address you see using ipconfig will be the same as that which you see reported by the "what's my IP" sites.

If you're behind a router (or a modem that is acting as a NAT router) then the internet IP address is actually assigned to the router. The router then hands out "local" IP addresses to the individual machines connected to it. Those are the "192.168." addresses you'll commonly see when running ipconfig. In fact, "192.168.x.x" is an invalid internet IP address, as that range, and a couple of others, are reserved exclusively for local network use.

When you're behind a NAT router, "ipconfig" will report your machine's local IP address, and the IP reporting web sites will show you your internet IP address.

When I enter "IPCONFG" in the command prompt as directed, I get a message that it is not recognized as an internal or external command, inoperable program or batch file. I am running Windows XP, SP3 Professional
Can you help?

If your comment is accurate, it's ipconfig not ipconfg - there's a second 'i'.

The command is IPCONFIG. Probably, the 'I' got left left out by mistake.

Type? You meant ipconfig for a windows machine.

This is for Robert Solarski (and everyone else!) --

You've managed to catch Leo in a rare error: he mannaged to misspell the command. It's not "IPCONFG", but "IPCONFIG" (a second "I" belongs between the "F" and the "G"). That's why you're getting CMD.EXE's equivalent of a "?SYNTAX ERROR".

Nyah nyah nyah, Leo! Shame on you! :) :) :)

It happens more often than I'd like. Thankfully I can always count on my readers to point out my errors. (Fixed it by the way.)

Be careful slinging the raspberries, Glenn P. !
"he mannaged to misspell the command"
contains a misspelling of its own!
("managed" contains but one "n")

:o :) :=)

Strictly speaking, 'machines' don't have IP addresses, it's network adapters that have an IP address! You'll have an IP address for each network card installed; thus your computer could have two or three!

Thanks, everybody, but I already figured it out, which I should have done before firing off my comment. It's nice to know that somebody else is not perfect.

Another way to find the IP Address is to go to the Internet and type in www.whatismyip.com. This works for only one networkcard. With more than one networkcard I don't know if it would show multiple IP Addresses.

As mentioned in the article services like whatismyip.com only show you your internet IP address, they do not and can not show you the IP address of your machine (er, your machine's network card) on your local LAN if you have a router.

This new web site will tell you BOTH your external address (like the other sites) but also the local IP address of your computer, and the IP address of your router. Now you don't need IPCONFIG!

does ip address behave like binary number ?

Mark J
June 13, 2011 12:05 PM

@Koushal
The real IP number is a binary number. What you see is the decimal representation of that binary number. Each group of 3 digits represents a group of 8 binary digits from 00000000 to 11111111. 11111111 base 2 = 255 therefor the highest number in that group of 3 can only be 255.

I ran ipconfig (on XP) but the resulting info flashes on screen for maybe about 1/10th sec. so unreadable. Tried several times.

You need to run it in a Windows Command Prompt. Start, Run "cmd", and then in the resulting window run ipconfig.

If you look at the header information in an email you get from that person, you can see the IP address where it was sent from.

I did a search to help me find out my ip address. Some were command prompt links , others "show me" links, so I kept getting two different addresses. Your article, succinct and easy for a newbie like me to understand, cleared it nicely for me. I've bookmarked your site and flagged it as "go to". Thanks for the good job!
