NS sets differ

The nameservers at the parent and in the zone should be the same. Only at the parent: ns1.plusnet.co.uk, ns2.plusnet.co.uk.

#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 one network

all IPv4 addresses are in 195.166.128.0/24. 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 (AS6871 (Plusnet - British Telecommunications Limited, GB): 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
✓ Nameserver names under 2 TLDs #12

Nameserver names use the TLDs .net, .uk.
!

No IPv6

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