Name servers cannot be cnames. The DNS protocol cannot be made to
work reliably when they are CNAMEs without changing the definition
of glue and the additional section processing rules. CNAME records
are NOT added as glue, A and are added as glue.

We're having a very similar problem to the thread "question about how a
particular dig works ...", in that "dig +trace" works and "dig" doesn't

This particular story is that someone didn't get a domain renewed in

And as you point out it has a cname at the apex ... which I thought was not
allowed.
Isn't it true that a cname record can't co-exist with any other record in a
zone file?
So if the soa record in the zone file is for www
