Basic bantypes and cloaked hosts
UtoNet supports the basic bantypes in the form of:
nick!user@host

If a masked host of someone is 'utonethide-ACB17294.isp.com' and a ban is placed as:
*!*@utonethide-ACB17294.isp.com
and then that user sets him or herself -x, and therefore the user's host becomes for example 'dial-123.isp.com' the ban will still match. Bans are always checked against real hosts AND masked hosts.

Bans that match against IP addresses are also available (eg: *!*@128.*) and are also always checked.

Bans on cloaked IPs require a bit of an explanation:
If a user has the IP 1.2.3.4 his or her cloaked host could be 341C6CEC.8FC6128B.303AEBC6.IP.
If you ban *!*@341C6CEC.8FC6128B.303AEBC6.IP you would ban *!*@1.2.3.4.
If you ban *!*@*.8FC6128B.303AEBC6.IP you ban *!*@1.2.3.*
If you ban *!*@*.303AEBC6.IP you ban *!*@1.2.*

Extended bantypes
Extended bans look like ~[!]<type>:<stuff>. Currently the following types are available:

Type:	Name	Explanation:
~q	quiet	People matching these bans can join but are unable to speak, unless they have +v or higher. Ex: ~q:*!*@blah.blah.com
~n	nickchange	People matching these bans cannot change nicks, unless they have +v or higher. Ex: ~n:*!*@*.aol.com
~c	channel	If the user is in this channel then she or he is unable to join. Ex: ~c:#lamers
~r	realname	If the realname of a user matches this then (s)he is unable to join. Ex: ~r:*Stupid_bot_script* NOTE: an underscore ('_') matches both a space (' ') and an underscore ('_'), so this ban would match 'Stupid bot script v1.4'.

The same information here about bans and ban types also applies to ban exceptions (+e).
