IRC

The Internet Relay Chat protocol (IRC) is similar to a Talker, in that it provides near-real-time text communication between a group of "nicknames" (users) connected to the same "channel" (chatroom) in an interconnected IRC server network. Server access requires using an IRC client. IRC uses the URI "irc://". There is never a delay or disconnect between users on the same server. A slow connection between users on different servers causes a condition known as "lag". A broken connection between users on different servers causes a condition known as "netsplit". Because IRC has a short packet size, and because messages can't span packets, keep lines under about 400 characters to prevent message truncation. Below is a list of public IRC server networks, with an associated address of their suggested round-robin pool server.
