Not to niggle on details, but that's CS as in CSNET, not CH as in
Chaos, and the phone number was the number of the host's dialup modem.

The 16 bit addresses for Chaosnet sound right.

Details aside, I entirely agree with your point that classes are
useless, and we should shut down registries, deprecate classes other
than IN, and so forth.  For classes to be useful, they'd have needed
well defined per-class boostrap and delegation, which they've never
had.

Whatever classes were supposed to provide we now get with separate DNS
trees with their own roots.  I gather there's a very widely used one
that supports GSM mobile phone roaming, with the root at Neustar.

R's,

PS: We briefly had a Chaosnet at Yale around 1980, for which I have
memories of one weekend when we wrestled the amusingly named
semi-rigid cable (semi-rigid in the same sense that a tire iron is
semi-rigid) through utility closets.
