2 nameservers

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

#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 85.158.211.0/24. 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 (AS8368 (DSTNY-BACKBONE - Dstny BE N.V., BE): 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 .be

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.
