=== Ports ===
The officially assigned port numbers are 194 ("irc"), 529 ("irc-serv"), and 994 ("ircs").<ref>[https://www.iana.org/assignments/port-numbers IANA.org]</ref> However, these ports are in the ''privileged'' range (0–1024), which on a [[Unix-like]] system means that the daemon would historically have to have [[superuser]] privileges in order to open them. For various [[security]] reasons this used to be undesirable.

The common ports for an IRCd process are 6665 to 6669, with 6667 being the historical default.<ref>{{cite journal|url=http://tools.ietf.org/html/rfc1459#section-5.6 |title=RFC 1459 – Internet Relay Chat Protocol |year=1993 |publisher=Tools.ietf.org |doi=10.17487/RFC1459 |access-date=2010-03-03|last1=Oikarinen |first1=J. |last2=Reed |first2=D. |url-access=subscription }}</ref> These ports can be opened by a non-superuser process, and they became widely used.
