[Cialug] TIL About DNS Classes

[Todd Walton]

I learned today that DNS is built to handle more than one "class", one of
which is the Internet. Once upon a time there was a Chaosnet and Hesiod,
both of which were something alternate to the internet.

BIND misuses the CH class for its own internal stuff. Check out this neat
trick:

$ dig CH @localhost authors.bind TXT
