2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns3.combell.net, ns4.combell.net.

#6
!

NS sets differ

The nameservers at the parent and in the zone should be the same. Only in the zone: ns1.combell.eu. ns1.combell.eu, ns3.combell.net, ns4.combell.net report NS ns1.combell.eu ns3.combell.net ns4.combell.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 3 IPv4 /24s and 3 IPv6 /48s.
✓ 2 autonomous systems #11

The nameservers are spread over: AS28747 (EASYHOST-COLO-AS - Easyhost BVBA, BE): 2 addresses; AS34762 (COMBELL-AS - Combell NV, BE): 4 addresses.

All nameserver names under .net

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.
