2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: hestia.mmsh.univ-aix.fr, ns4.cnrs.fr.

#6
!

NS sets differ

The nameservers at the parent and in the zone should be the same. Only at the parent: hestia.mmsh.univ-aix.fr; only in the zone: hestia.mmsh.fr. hestia.mmsh.fr, hestia.mmsh.univ-aix.fr, ns4.cnrs.fr report NS hestia.mmsh.fr ns4.cnrs.fr.

#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 different networks #10

The nameservers are spread over 2 IPv4 /24s and 1 IPv6 /48.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS2200 (FR-RENATER - Renater, FR): 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 .fr

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
i

Partly IPv6

These nameservers have no IPv6 address: hestia.mmsh.fr, hestia.mmsh.univ-aix.fr.
