There's also https://dnssec-analyzer.verisignlabs.com/ but it is also
mainly about DNSSEC.

(Worth noting that when you update a domain object in the RIPE database,
it uses Zonemaster to check that the new setup is cromulent.)

I wouldn't point a user at any of these unless I think they have a good
amount of DNS expertise :-)

In my work many of the difficult or time-consuming support issues are
related to domain registration rather than DNS, so I have Mixed Feelings
about the state of whois etc.
