You would still need a valid hostname. the /DNS command for example, doesn't give the actual hostname all the time. You need the address or name of the users actual PC to establish a direct netmeeting connection, similar to the peer to peer DCC connection.
I would need the users actual hostname to resolve it in my plugin. Many servers don't even display actual hostnames anymore.
Thanks for the reply. I think what i am looking for is a magic mirc command like:
/IP nickname
that returns the users IP address

Also, I don't see where I have a 'looking at' turned off.
