A Short History of Chaosnet

Looking into DNS records, you’ll find a trace of a little-known LAN-only protocol… which postdates early TCP/IP but is unrelated to it:

The only really visible remnant of Chaosnet is the CH DNS class. There’s something about that fact that I find strangely fascinating. The CH class is a vestigial ghost of an alternative network protocol in a world that has long since settled on TCP/IP. It’s exciting, at least to me, to know that the last traces of Chaosnet still lurk out there in the infrastructure of our networked society. The CH DNS class is a fun artifact of digital archaeology. But it’s also a living reminder that the internet was not born fully formed, that TCP/IP is not the only way to connect computers to each other, and that “the internet” is far from the coolest name we could have had for our global communication system.

That’s a great blog - sadly a tad dormant ATM.
