In November 1988, IRC had spread across the Internet and in the middle of 1989, there were some 40 servers worldwide.
In August 1990 the first major disagreement took place in the IRC world.
For the latter purpose, the Undernet implemented timestamps, new routing and offered the CService—a program that allowed users to register channels and then attempted to protect them from troublemakers.
Internet Relay Chat (IRC) is an application layer protocol that facilitates communication in the form of text.
The chat process works on a client/server networking model.
IRC was created by Jarkko Oikarinen in August 1988 to replace a program called MUT (Multi User Talk) on a BBS called Oulu Box at the University of Oulu in Finland, where he was working at the Department of Information Processing Science.
Jarkko intended to extend the BBS software he administered, to allow news in the Usenet style, real time discussions and similar BBS features.
On August 15, the new user count record was set to 57 users.
which led various implementations of servers and clients to diverge.
The "A-net" (Anarchy net) included a server named eris.
It was all open, required no passwords and had no limit on the number of connects.
Another fork effort, the first that really made a big and lasting difference, was initiated by 'Wildthang' in the U. October 1992 (it forked off the EFnet ircd version 2.8.10).
It was meant to be just a test network to develop bots on but it quickly grew to a network "for friends and their friends".
In Europe and Canada a separate new network was being worked on and in December the French servers connected to the Canadian ones, and in the end of the month, the French and Canadian network was connected to the US one and the network that later came to be called "The Undernet" was born.
