will only send the address, not the entire host, by the way, its not safe send the host, with the ip

i'm not sure what you're trying to say here. $ial($me).addr returns the ident@host that the server sends you and everyone else that ever receives server messages concerning your client. it is the very same ident@host that users will see when you later /quit. the fact that he adds ~ to the ident leads me to believe that what he is aiming to get is precisely this information.

$host, on the other hand, does not necessarily return information that is available to other clients. if the network has host hashing and mIRC uses a server lookup method to resolve a named host from your IP, then $host will reveal your real host (and, consequentially, your IP) whereas $ial($me).addr and $ial($me).host would not.

ultimately, the OP would need to clarify what information it is he's trying to display - chances are that it is simply $ial($me).addr.
