i

.fr is a country-code TLD (ccTLD)

Country-code TLD: governed by its local registry under national policy, not by an ICANN contract. Registrar accreditation, dispute resolution and RDAP/WHOIS rules are set by the registry.

#1
✓ TLD delegated and signed #2

.fr is delegated in the root zone and DNSSEC-signed.

2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns3.dns-iol.com, ns4.dns-iol.com.

#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.
✓ 2 autonomous systems #11

The nameservers are spread over: AS15557 (LDCOMNET - Societe Francaise Du Radiotelephone - SFR SA, FR): 1 address; AS41894 (INFORMATIQUE-AS - INFORMATIQUE ON LINE SAS, FR): 1 address.
i

All nameserver names under .com

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

!

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns3.dns-iol.com: "9.5.2-RedHat-9.5.2-1.fc10"; ns4.dns-iol.com: "9.18.39-0ubuntu0.22.04.7-Ubuntu". 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: ns3.dns-iol.com (80.118.141.7): dial tcp 80.118.141.7:53: i/o timeout.

#19
✓ EDNS supported #20

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

All nameserver addresses are publicly routable.
