-In the Chaosnet [[https://github.com/bictorv/chaosnet-bridge|bridge program]], there is support for a ''DNS'' server over Chaosnet (using a "simple" connectionless protocol and forwarding/recursion over UDP) so Chaos-only hosts can make use of it. See [[https://github.com/bictorv/chaosnet-bridge/blob/master/CONTACTS.md|cbridge documentation]] for a protocol description.

-At DNS.Chaosnet.NET, there is also a server for the ''DOMAIN'' contact name which allows DNS queries over a stream connection, lifting the response size limit of the simple protocol (488 bytes). This contact is more standard, used by Symbolics lisp machines, and (soon) by the [[https://www.bogodyne.com|Bogodyne]] lisp system.

+At HOSTAB.Chaosnet.NET, there is also a server for the ''HOSTAB'' contact name, which is higher-level (see [[https://chaosnet.net/amber.html#Host-Table|here]]) and used by Lisp machines such as CADR and Lambda.

-:NOTE: This seems to work **better** than my previous "static-stub" config, which causes (2021-03-30) bind9 to crash occasionally (again, caused by confusion between DNS classes). You might want to configure your bind9 service to restart automatically on a crash, see https://ma.ttias.be/auto-restart-crashed-service-systemd/.

 If you do host your own Chaosnet data, here is an example (but see below about secondary name servers):

 Network names also appear in CH-ADDR.NET, in the spirit of [[rfc>1101|RFC 1101]]. They are at labels corresponding to the subnet address with zero host part, e.g. 400.CH-ADDR.NET for subnet 1, 3000.CH-ADDR.NET for subnet 6, etc.

 :NOTE: If you have a stable server machine with a static IP address and can open port 53, maybe you want to be secondary nameserver for the Chaosnet zones? Let me know!
