What is a hostmask?
Up to table of contentsEach user on IRC is uniquely identified by a string which we call a "hostmask." The IRC RFC refers to it as a prefix. Either way, it consists of a nick, a user, and a host, in the form nick!user@host. If your Supybot complains that something you've given to it isn't a hostmask, make sure that you have those three components and that they're joined in the appropriate manner.
