2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns.heartinternet.uk, ns2.heartinternet.uk.

#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 different networks #10

The nameservers are spread over 2 IPv4 /24s and 0 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS20738 (GD-EMEA-DC-LD5 - Heart Internet limited, GB): 2 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 .uk

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
!

No IPv6

None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

#13

✓ All respond #14

All 2 nameserver addresses answered.
✓ All authoritative #15

Every responding nameserver answers authoritatively for the zone.
✓ No recursion #16

The nameservers do not answer recursive queries for other domains.
!

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns.heartinternet.uk: "Served by POWERDNS 3.1 $Id: packethandler.cc 2579 2012-04-26 11:28:04Z peter $"; ns2.heartinternet.uk: "Served by POWERDNS 3.1 $Id: packethandler.cc 2579 2012-04-26 11:28:04Z peter $". Hide or replace the version string.

#17
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
✗

No DNS over TCP

DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: ns.heartinternet.uk (79.170.40.2): read tcp 46.225.38.91:35254->79.170.40.2:53: i/o timeout; ns2.heartinternet.uk (79.170.43.3): read tcp 46.225.38.91:38254->79.170.43.3:53: i/o timeout.

#19
!

No EDNS

These nameservers don't support EDNS(0), needed for DNSSEC and answers larger than 512 bytes: ns.heartinternet.uk (79.170.40.2), ns2.heartinternet.uk (79.170.43.3).

#20
✓ Public addresses #21

All nameserver addresses are publicly routable.
