How to find the WAN ip for a connected computer

StackOverflow https://stackoverflow.com/questions/21173474

Question

I have been trying to get the IP of a person on my network, so I tried pinging them and finding their ip on my network site, but it didn't give me their WAN ip. Please help.

Was it helpful?

Solution

if the client is in your network you will probably stay in your LAN - therefore you will get the response from the private IP of course. the WAN IP is only used when the client tries to access some IP on a public range.

one option is to ask the client to visit something like http://www.whatismyip.com/ and tell you the output or host a service yourself that is doing something similar.
