How can I use two ip addresses from one cable modem?

Some cable ISPs configure your cable modem with only 1 IP address by default and charge a few dollars a month for extra addresses. If your ISP only provides you 1 address, a router would be required to share that address between your computers.

A special case where you might WANT something like described in the article;

- you have a home network behind one router (using your first IP address)
- you have a server with your second IP address

So now, your server is now 'isolated' from your home network; which should make your home network more secure (since potential hackers won't be able to get to your 'home network' THROUGH your now isolated sever)

Another case might be if you want to seperate two groups of people (so that each group is 'isolated' from each other) ie. So Group A can't get onto Group B's network and visa versa.

What connecting one computers on two ip by one cable(wi-fi site)

i have ip, what i make detect how many computers working on this ip? hmmm?

simple fix to get 2 ip's on 1 line, why couldn't i think of that...you're the man!

Hello,
I am trying to set-up 2 ips in my house. My provider gives me 3 ip addresses, which right now I am only using one of course. My question is do I need a separate router (2) for each ip address? Right now I have a wireless route that connects two computers, xbox, 3 playstations. But I need to take advantage of at least one more of the ip addresses for a different computer (this computer is for a room-mate which needs a different ip address). So do I follow the same directions above by getting another router and hub?

Thanks, Amy

Hi,
I need to do this, but im using two dynamic ip addresses, I was woundering if insted of using a hub, could you use a switch. I have a switch I am not useing. I want this to seperate my one xbox from the other because I get network errors with them on the same network. Thanks for any help!

My router alows me 5 ip addresse and I nee 10. Howdo I make that happen.

I have a high-speed line coming in to my home with DHCP for my initial wireless router (D-Link). DHCP is running on that router. Behind that, I would like to place another wireless router that would serve a separate section of the house (Netgear). I purchased a second router because it was cheaper than an access point. Did I make the wrong decision?

on your comment, How can I use two ip addresses from one cable modem, i want to ask if i can use switch instead of hub.
