The IRC dissector is not in the latest public build. XXX - Add example traffic here (as plain text or Wireshark screenshot). The well known TCP port for IRC traffic is 6667. TCP: Typically, IRC uses TCP as its transport protocol.The average number of users connected to IRC networks has continuously grown since 1989 at an alarming rate. Now it supports a large number of world-wide network sof servers and clients, and is stringing to cope with growth. The IRC protocol began development in 1989 and was first implemented as a means for users on a BBS to chat amongst themselves. A typical setup involves a single process (the server) forming a central point for clients (or other servers) to connect to, performing the required message delivery/multiplexing and other functions. IRC itself is a teleconferencing system, which (through the use of the client-server model) is well-suited to running on many machines in a distributed fashion.

The IRC protocol has been developed on systems using the TCP/IP network protocol, although there is no requirement that this remain the only sphere in which it operates. (from RFC 1459) The IRC (Internet Relay Chat) protocol has been designed over a number of years for use with text based conferencing.
