nsd users - Jan 2024 - support for ALIAS records

Hi Christof!

AFAIK, PowerDNS is the only open source name server that supports ALIAS. There
was an idea to standardize ALIAS as "ANAME"
(https://datatracker.ietf.org/doc/draft-ietf-dnsop-aname/), but the idea was
dropped in favor of SVCB/HTTPS record https://datatracker.ietf.org/doc/rfc9460/.
So now we have to wait until all Browser vendors implement SVCB/HTTPS.

Regards
Klaus

PS: If you build something new, don't use ALIAS, it can cause you problems
later due to incompatibilities

While SVCB/HTTPS provides a better solution for the browsing use case, I see
other use cases where ALIAS/ANAME would be ideal, notably in apex RRs.

So while fostering SVCB/HTTPS deployment is a good thing, I wouldn?t mind name
server software implementing ALIAS. Including NSD, but I reckon it?s much more
challenging to do due to NSD architecture than it was to implement it in
PowerDNS.

But if NSD developers some day feel bored, perhaps implementing ALIAS would
solve that ? ;-)
