2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns1.masterdns.nl, ns2.masterdns.nl.

#6
✓ 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 one network

all IPv4 addresses are in 185.168.85.0/24; all IPv6 addresses are in 2a0a:9fc0:1053::/48. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).

#10
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS31673 (UNISERVER-AS - Uniserver Internet B.V., NL): 4 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 .nl

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.

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.masterdns.nl: "PowerDNS Authoritative Server 4.3.2 (built Mar 8 2021 10:28:08 by root@5b0daa176133)"; ns2.masterdns.nl: "PowerDNS Authoritative Server 4.3.2 (built Mar 8 2021 10:28:08 by root@5b0daa176133)". Hide or replace the version string.

#17
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
✓ TCP supported #19

All nameservers answer over TCP.
✓ EDNS supported #20

All nameservers support EDNS(0).
✓ Public addresses #21

All nameserver addresses are publicly routable.
