Now, to determine if a user other then yourself is using a vhost.. its fairly easy. Just look for usermode +x set to the user. (For unreal-ircd that is) This indicates that either the user is using a vhost, OR has their ip/host masked via ip encryption.
In Unreal IRCd, usermode x shows that their host is masked(e.g. 34fc87.43217f.314f85.IP, IRC-adb493.ipt.aol.com), usermode t shows that they are using a nonstandard mask(e.g. my.cool.vhost).
