Hi!

I've now met a problem where I don't know how to proceed:

===========>% ===========
C:\Users\kolbrich>nslookup -q=CNAME _
91867ab3c77f152ba4ab0cceeabb3666.expose.graf-borstar.de. 8.8.8.8
Server:  dns.google
Address:  8.8.8.8

Nicht autorisierende Antwort:
_91867ab3c77f152ba4ab0cceeabb3666.expose.graf-borstar.de        canonical
name = _c09668a36b3b6665549a795863f30b9b.olprtlswtu.acm-validations.aws
===========>% ===========

My NS has a catch-all zone using "." including SOA to be authoritative for
all new domains that do not yet have a zone (async processing).
This allows us to be responsive for zones we actually did not yet create or
have not been replicated.

It's seems, that AWS uses the same authoritative NS to resolv it's own
CNAME (which does not resolve at all in public):

  ===========>% ===========
C:\Users\kolbrich>nslookup
_c09668a36b3b6665549a795863f30b9b.olprtlswtu.acm-validations.aws.
10.100.0.210
(root)
        primary name server = ns01.srvfarm.net
        responsible mail addr = dnsnoc.dolphin-it.de
        serial  = 2
        refresh = 10800 (3 hours)
        retry   = 3600 (1 hour)
        expire  = 604800 (7 days)
        default TTL = 3600 (1 hour)
Server:  UnKnown
Address:  10.100.0.210

Name:    _c09668a36b3b6665549a795863f30b9b.olprtlswtu.acm-validations.aws
Addresses:  2a06:9500:1002:0:185:118:197:123
          185.118.197.123
  ===========>% ===========

Do I need to adjust the "graf-borstar.de"-zone? If yes, how?
I am running dnsdist in front, should I adjust something there?

Kind regards
Kevin
