✓ 6 nameservers #6

Delegated to a1-22.akam.net, a16-65.akam.net, a2-67.akam.net, a6-65.akam.net, a7-66.akam.net, a9-66.akam.net.
✓ 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 6 IPv4 /24s and 6 IPv6 /48s.
✓ 2 autonomous systems #11

The nameservers are spread over: AS20940 (AKAMAI-ASN1 - Akamai International B.V., NL): 1 address; AS21342 (AKAMAI-ASN2 - Akamai International B.V., NL): 11 addresses.
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.

Very low TTLs

These records have a TTL below 5m, causing extra queries and slower lookups: A (20s), AAAA (20s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 4h; resolvers may use either.
