now odviously there are numerous legitimate reasons to know someone elses i.p. such as a way to report an attack on yourself to there isp. etc.. lets not freek out he wants to know how to get an i.p. not the passwords to the NORAD defense network.



heres a few other ways i thought ide add to the list,

if your on irc, type /dns username to get the i.p

you can use webcarnage's method if you use aim, icq, etc.. just send or accept a file tranfer and do what he said

another way to do it is to get them to email you, try telling them your hotmail account is screwed up and you want them to mail you and see if it works then look in the header for the adress

there are numerous different tools that will work on aim, trillian, icq, etc... just search
