Is it possible for two computers to have the same IP Address?

Can a computer in say North Carolina have the same IP Address as a computer in Tokyo, Japan? Or can two computers anywhere have the same IP Addresses? Thanks!

Yes they can ... sort of. But not really.

Many times a company will have one IP address for the outside world and make an internal network behind a gateway with a different set of network addresses. There are some ip addresses that have been set aside expressly for this puropose. 192.168.x.x is one example. A gateway/router will not make such an address visible to the outside world, but will make it visible to other computers in the internal network.

For example, my computer's network address is 192.168.2.20. It is only reachable within my home network through my gateway router. There is probably another computer with the same ip address on another network somewhere. However because the address is set aside for internal uses only, there is no conflict. Both computers are reachable only through gateways that MUST have a unique ip address.

An IP address uniquely identifies every computer on the internet.The key word there is unique.

If two computers on the same network have the same IP address ... well, the results are unpredictable. It depends on how all the other equipment on the network handles the problem. In general it could be as bad as both machines not being able to communicate at all. More likely only one will not be able to, or perhaps there will simply be intermittent problems on both.

In short: don't do it.
No there unique i think if someone uses a proxy or something similar they can imitate a Ip
No
no unless if it's using the same way of getting the connection ex.
