CNAME flattening

NSD
1

Hi everyone,

I was pointed to a blog post about CNAME Flattening[0] which, AFAIU,
technically boils down to this excerpt from the post:

»What we needed was a way to support a CNAME at the root, but still
follow the RFC and return an IP address for any query for the root
record. To accomplish this, we extended our authoritative DNS
infrastructure to, in certain cases, act as a kind of DNS resolver.
What happens is that, if there's a CNAME at the root, rather than
returning that record directly we recurse through the CNAME chain
ourselves until we find an A Record. At that point, we return the IP
address associated with the A Record. This, effectively, "flattens" the
CNAME chain.«

This seems like a very handy feature and I could have used it a couple
of years back as well, hence my questions:
Is there any plan to introduce this to NSD?
Has it been discussed already? If so, please point me there.
Could it be considered as a future feature please?

Thank you and best regards

Hi everyone,

I’m a bit surprised that nobody replied at all to this post.
AFAIU there is a real need for a few real-world use cases.
Does really not one person have any further information or opinion on
the topic?
Pretty please respond what you think about this subject, I really care
to know!

Thank you and best regards

Hendrik

PS: This is just a one-time resurrect, I will not be doing that again
if there are no replies this time, either.
