2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns23.sys.ccs-baumann.de, ns42.sys.ccs-baumann.de.

#6
✓ Parent and zone agree #7

The parent delegation and the zone's NS records list the same nameservers.
✓ No glue needed #8

All nameservers are outside the zone, so no glue records are needed.
✓ All names resolve #9

Every nameserver name has an address and is not an alias.
✓ Nameservers in different networks #10

The nameservers are spread over 2 IPv4 /24s and 2 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS24940 (HETZNER-AS - Hetzner Online GmbH, DE): 4 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.

#11
i

All nameserver names under .de

All nameserver names are under one TLD, so a problem with that TLD also makes the nameservers unreachable. Some operators use names under two TLDs for extra resilience.

#12
✓ All reachable over IPv6 #13

Every nameserver has an IPv6 address.

Nameservers not responding

These addresses did not answer, so resolvers waste time on timeouts: ns23.sys.ccs-baumann.de (78.46.102.24): read udp 46.225.38.91:53167->78.46.102.24:53: i/o timeout; ns23.sys.ccs-baumann.de (2a01:4f8:120:91bf::2): read udp [2a01:4f8:1c1c:eebf::1]:39441->[2a01:4f8:120:91bf::2]:53: i/o timeout.

#14
✓ All authoritative #15

Every responding nameserver answers authoritatively for the zone.
✓ No recursion #16

The nameservers do not answer recursive queries for other domains.
i

Identifying string disclosed

These nameservers answer version queries with a string that is not a version number: ns42.sys.ccs-baumann.de: "Here be kittens".

#17
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
✓ TCP supported #19

All nameservers answer over TCP.
✓ EDNS supported #20

All nameservers support EDNS(0).
✓ Public addresses #21

All nameserver addresses are publicly routable.

TTLs: A 10m, AAAA 10m, MX 1h, NS 1d. The NS TTL at the parent is 2d and in the zone 1d; resolvers may use either.
✓ No CNAME at the apex #33

The zone apex has no CNAME record.

Wildcard record

A random name under the zone resolves, so there is a wildcard (*) record. Typos and non-existent hosts resolve too, which can confuse mail and certificate checks.
