ircII (pronounced irc-two, and sometimes referred to as IRC client, second edition) is a free, open-source Unix IRC and ICB client written in C. Initially released in the late 1980s, it is the oldest IRC client still maintained. Several other UNIX IRC clients, including BitchX, EPIC, and ScrollZ, were originally forks of ircII. For some, ircII set the standard of quality for IRC clients, however other clients may have overtaken ircII in recent years in terms of popularity. The application has been promoted as being "fast, stable, lightweight, portable, and easily backgrounded".

ircII runs in a text-only sell-based environment. The application has no sounds, menus, pop-ups, or any other GUI features that other IRC clients, such as mIRC, typically have.

ircII was the first IRC client to implement Client-to-client protocol (CTCP) and the Direct Client-to-Client (DCC) protocol, and was the first client to implement file transfer capabilities over IRC. The CTCP protocol was implemented by Michael Sandrof in 1990 for version 2.1. The DCC protocol was implemented by Troy Rollo in 1991 for version 2.1.2, but was never intended to be portable to other IRC clients.

However, the other main variant, "irk-two" is probably historically more accurate. It's also commonly called "urk-ee" which is most definitely wrong. Feel free to disagree with us, we're not going to argue the point to death. What's pretty certain is that it is "two" and not "ee".

The first comment I should make is that the DCC protocol was never designed to be portable to clients other than IRCII. As such I take no responsibility for it being difficult to implement for other clients.
