The "might be" can be modified into "has been" delegated. Thus I am
currently setting up my PTRs, and I have to learn the Knot way ;-) (10+ years ago I did
this with bind)
Hereby I
stumbled over the module synthrecord and do not really understand what it is used for.
From
https://www.knot-dns.cz/docs/3.4/singlehtml/index.html#synthrecord-automati…
"Records are synthesized only if the query can't be satisfied from the
zone."
Please excuse my ignorance, but why would/should/must one return something else than the
following for hosts not in the zone?
those are PTR records and are essential for things like email (learndmarc.com is a good
resource that checks for this) > "Records are synthesized only if the query

Why would/should/must one return something like (from the link above) …
kdig -x 2620:0:b61::1
...
