Features

IRC server features, mostly extensions to RFC 1459. Probably also implementations of RFC 2810, RFC 2811, RFC 2812, RFC 2813, and possibly IRCX.

  • +channels (In early IRCds, these were simply named channels. At least one modern IRCd (IRCD) uses the + prefix for modeless channels, i.e. no modes are supported other than +t, which is forced. Since no user can become a chanop, no topic can be set. This is described in RFC 2811.)
  • #channels ("+channels" were later replaced with "#channels" in version 2.7, numeric channels were removed entirely and channel bans (mode +b) were implemented.)
  • &channels (irc2.8, those that exist only on the current server, rather than the entire network)
  •  !channels (irc2.10, those that are theoretically safe from suffering from the many ways that a user could exploit a channel by "riding a netsplit"; IRCds using timestamping provide (most of) this functionality on #channels)
  •  %#channels (#channels whose name are in UTF-8 for IRCX)
  •  %&channels (&channels whose name are in UTF-8 for IRCX)
  •  %!channels (!channels whose name are in UTF-8 for IRCX)
