NS sets differ

The nameservers at the parent and in the zone should be the same. Only in the zone: ns1.m-online.net, ns2.m-online.net. dns1.odn.de, dns2.odn.de, dns3.odn.de, ns1.m-online.net, ns2.m-online.net report NS dns1.odn.de dns2.odn.de dns3.odn.de ns1.m-online.net ns2.m-online.net.

#7
✓ 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 5 IPv4 /24s and 2 IPv6 /48s.
✓ 2 autonomous systems #11

The nameservers are spread over: AS12348 (AS12348 - ODN OnlineDienst Nordbayern GmbH & Co. KG, DE): 6 addresses; AS8767 (MNET-AS - M-net Telekommunikations GmbH, DE): 3 addresses.
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.

✓ TTLs within range #32

TTLs: A 5m, MX 5m, NS 5m. The NS TTL at the parent is 1d and in the zone 5m; 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.
