Is there anything I can do with my hackers IP address?

Hi guys, I'm pretty sure I know who has been recovering my account but I am trying to see if his IP address matches the one that last logged onto the account I just recovered. I know this individual in person and am 'friends' with him online, but he keeps insisting that he gave the account to one of his friends who is behind the account recovering. Is there anyway I can find out his IP address inconspicuously to see if it matches the one that last logged onto my account?

Thanks

 

Contact a global to see if it matches a IP from a sythe user. Don't post it or do anything with it on sythe or else you will be banned.

 

You can check an IP with msn messenger.

Send it to me in a PM and who you suspect it of being
