Channel Type Prefixes

Revision 1.60

Red denotes a conflicting numeric definition, gray for deprecated (however quite possibly still in use), and blue for OK.

Prefix	Name	Origin	Creatable	Comments
&	LOCAL	RFC1459	Y	This channel type is known only to the server they are created on, and as such only clients on that server can join it. Each instance of this channel type is contained per server.
#	NETWORK	RFC1459	Y	This channel type is known to all servers that are connected to the network.
!	NETWORK_SAFE	RFC2811	Y	These channels work similar to the `'#'` channels, except the name is prefixed not only with the `'!'` but also a set of alpha- numeric digits. This is an alternative to the time-stamp method of avoiding channel-takeovers during network splits.
+	NETWORK_UNMODERATED	RFC2811	Y	These unmoderated channels work almost exactly the same as `'#'` channels, except nobody can obtain channel operator status on them. Some implementations seem to set the channel mode to `'+nt'` upon creation, however most implementations act as if modes `+nt` are set but don’t announce them as being set.
