2 nameservers

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

#6
!

NS sets differ

The nameservers at the parent and in the zone should be the same. Only at the parent: ns3.online.net, ns4.online.net; only in the zone: ns0.online.net, ns1.online.net. ns0.online.net, ns1.online.net, ns3.online.net, ns4.online.net report NS ns0.online.net ns1.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 3 IPv4 /24s and 3 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS12876 (AS12876 - Scaleway SAS, FR): 8 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 .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.
