I've made extensive use of CHAOS class records in the past. Not for

class. I'm running 9.12.1-P2. I was surprised to see this, though it
has been probably 25 years since I'd used CHAOS. I wonder when support
for this was removed.
I think it should still be supported. One of the servers here at Update
is running 9.11.5-P4 and is serving up a few CHAOS zones, and I couldn't
find anything mentioning support for it being removed in newer versions.

"KLH10" "ITS"
I think the CHAOS zones has to go under a separate view, though.
Second,
some issues with MAIL-11 and DECnet SMTP on Tops-20 have
caused me to believe that one solution would be to expand the DNS
service (CHIVES) to handle A and MX records for DECnet.? That's not
actually that big a stretch; the DNS specification has 16 bit data
types for CHAOS, which would be trivially re-usable for Phase IV
DECnet.? However, I'm finding the current documentation to be a chore
to wade through.? The source code incomplete in certain functionality.
I seriously doubt you'd ever get this to play. Not only do I think that
CHAOS, even though it technically exists, are tested or supported by any
name server today. I also can't really see how you think adding DNS
would solve any problems you might have with MAIL11. There is an "internal" special record type
supported by BIND, class
CHAOS, type TXT, name version.bind, that returns the version number of
the BIND software, but this is not tied to zone files and I don't
believe (though I've not verified this) that it supports arbitrary data
of the CHAOS class.
