- n. On IRC, a partial address that matches a number of hosts.
Basically, a hostmask is a way of allowing someone to use an arbitrary nickname but still have an easily-checked public link to their role on a project (e.g. developer, core, etc).
Now that we are identified to NickServ, we need to add our hostmask to the access list.
For those who are not IRC gurus, here's a hostmask tutorial.
Rules allow you to op, voice, or even ignore a user based on their hostmask.
As with the normal message splitting, this is aware of how multi-byte/variable-width text encodings and sender hostmask length (which is part of the message on the receiving end) factor into the matter.
