Basic Information
IRC, initially a plain text protocol, was assigned 194/TCP by IANA but is commonly run on 6667/TCP and similar ports to avoid needing root privileges for operation.
A nickname is all that's needed to connect to a server. Following connection, the server performs a reverse-DNS lookup on the user's IP.
Users are divided into operators, who need a username and password for more access, and regular users. Operators have varying levels of privileges, with administrators at the top.
