determine ip address

hi, i would like help about how can two hosts, A and B
find eachother's ip addresses. both are home computers so that their ip addrs are dynamic...

Ok i dont know if this is a good way of doing it, or if its going to be any help at all but what u can do is make the program upload your current IP address onto an internet website, and then have the other client download that file and parse it for the IP file inside.

Hope this helps.
