✓ 3 nameservers #6

Delegated to ns0.transip.net, ns1.transip.nl, ns2.transip.eu.
✓ 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 3 IPv4 /24s and 3 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS20857 (TRANSIP-AS - Signet B.V., NL): 6 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.

#11
✓ Nameserver names under 3 TLDs #12

Nameserver names use the TLDs .eu, .net, .nl.
✓ All reachable over IPv6 #13

Every nameserver has an IPv6 address.

NSEC3 with extra iterations or salt

NSEC3 uses 0 iterations and a 8-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.

Very low TTLs

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