How can you have the same IP from two PCs? It seems like it would be easier to get two IPs than to request an IP exception. Are you using a router?
Just for clarity, here is a quick explanation. The two computers do have different ips, but the ips they have are referred to as private ip addresses; typically something like 192.168.0.1 - 192.168.1.255 range (not always). The two computers are thebln connected to your router which acts as the gateway with a 192.168.0.1 or 192.168.1.1 ip address.

Now your router also has a public ip address which is given to you by your internet service provider. Public ips are unique and a residential house typically only has 1, unless you pay extra. If you get into each computer and google search ipchicken, you will see the same public up address; whereas is you go into cmd and use the command ipconfig, you will see a different private ip that is assigned to you via your router.

Your router communicates to your isp via your public ip and routes traffic to your internal home local network (nat traversal)...or port forwarding.

What project1999 prevents is more than 1 MAC address per public ip.. so in order to play with 2 computers in the same household you are forced to request an ip exemption according to the rules.

This can be a explained much better and way more in depth, but I am on my cell phone.
