Generally, you will see your IP address and anyone else will see your host address. The exception to this is if the person looking is an IRCop, in which case they can see both.
If you want to see your host address, rather than IP, you can get it by doing //echo -a $gettok($address($me,5),-1,33)
This will show you your host address, in the format you specified, and only to you.
