[Guest_imported]

how can this be? my ip came back the same as someone else on a survey i had set up in my webpage. (it tells me the remote host) we had the exact same ip. how could this be?? sorry if this doesn't make sense.

there are classes of IP addresses that are 'Private' and can be repeated on different internal networks

192.168.x.x is very common
I tried to remain child-like, all I acheived was childish.

I would guess that jimbopalmer has this correct, and you are using an RFC 1918 Private Network address. There is a single class A subnet, 10.x.x.x, 16 class B subnets, 172.16.x.x - 172.31.x.x, and 255 class C subnets, 192.168.x.x. If your addresses fall anywhere within these ranges, then you are seeing the private network addresses, which are not routable on the internet. They can be duplicated on any private network as frequently as desired.

That also means that you are NATing somewhere along the line, probably at your DSL or cable modem.

Another possibility is that you are going through a proxy server, either on your local network, or your ISP is running one. In this case, the IP of your proxy may show up rather than your actual IP.

What does the script look like that you are running to query the remote end for its IP address?

420guest,

What mechanism are you using for htis survey on your webpage? Are you interrogating the browser? or asking the user to fill in their IP?

Chances are you are getting an address as described by jimbopalmer or pansophic. Addresses have to unique within their private address spaces but there can be many private spaces having the same addresses. It is not a conflict unless those addresses are repeated in the public space (internet).

Hope that helps.
