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

Well, you certainly can, but in most cases it only makes things more complicated than they need to be.
•
To actually do it, I'd put a hub in front of the two routers. So your cable modem would go into the hub, each router would be connected to the hub, and each would configured to respond to one of your two static IPs. You could then connect your computers to one router or the other, as you saw fit.
I'm just not sure why, in most cases, you'd want to do so.
The drawback here is that your machines on one router will not be able to share folders or printers with machines on the other router. Each router represents its own private sub-network on the internet.
Multiple internet IP addresses are really only useful if you have multiple computers that you want to access from the internet. For example you might want to set up two web servers, in which case each would need its own IP address. For most common home and small business situations, that kind of setup is actually pretty rare.
My ISP has allocated me 5 IP addresses here at home, but I use only one. All the computers in my house (8, I think) are connected behind a single router. I really don't have any need for the other 4 IP addresses at this time.
I suspect that, unless you're doing something special, you really only need one of your two IP addresses. It'll certainly be the simplest approach.

Took me 2 days to figure out, thought I'd post it for others the easiest way to get two playstation's running simultaneously on a home network is to use a Switch and make sure your ISP provides you with 2 IP addresses. You'll NEED 3 IP addresses if you plan to use any other computers on the network. Use the router to separate the rest of the network from the two ps3. Use wired connections for the PS3.
Setup
MODEM
-SWITCH
--1 PS3
--2 PS3
--Router
---PC1
---PC2
---WIRELESS LAB TOP
---ETC...
This setup will guarantee your able to join parties together in seconds(no waiting time or party kicks)
You shouldn't ever be kicked out of game by connection errors. (typical problem with this game)
Which means you won't get penalized for the game's inability to support all routers properly.
(why don't games collaborate with a router company, like a certified PS3 Router)
Uncharted unlike most other games has serious problems finding players, joining parties, or disconnecting from games, after testing, configuring many routers, opening ports, static ips, dmz, firewalls, routing ips, qos engine priorities, etc. your just wasting your time! If your not experiencing problems, great! ignore this, but if you are, don't waste your time!, get the setup i mentioned above and you will be set gaming for 10 hours straight together with your brother or sister watching others get disconnected .
Spread the word! this is specifically for Uncharted 2, connect directly and you won't have a problem anymore. Hopefully Uncharted 3 will have fixed these network issues. Enjoy!
THANKS BIG TIME TO LEO FOR THIS ARTICLE THAT HELPED ME SOLVE THE PROBLEM :P

I have 2 PC's and 2 IP addresses,each pc recognizes 1 IP address. I have it connected internet cable to modem,from modem to a linksys 5 port switch and from there a network cable to each pc works great. I did this because when I had 1 IP address and used a router my buddy and I would go to same online game play for a while but then get kicked, not sure if server saw us as one in the same. Anyway someone said if I got 2nd IP address and connected as above game server wouldn't kick us and it never has since. Each pc always has the same IP address they never switch back and forth.How does each pc recognize same IP address everytime you boot them ?

You should change the title of this article to something like "Should I use two IP addresses from one cable modem."
This is the antithesis of a how-to article. Instead of explaining how to do it, it argues against doing it at all. I'm wonder if you even know the answer to the question in the first place.

Much of Leo's advice seems to be pitched at the home user rather than the corporate sector/pure technical advice sector.
That advice appears to try to determine what the home user/writer is trying to achieve and he gives advice that he feels would be more appropriate to their needs.
Many replies appear to be not strictly from the "workshop manual "
