.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.
✓ Expires on 2026-12-07 #3

The registration is valid until 2026-12-07 (46 days).

✓ Parent and zone agree #7

The parent delegation and the zone's NS records list the same nameservers.
✓ Glue present and correct #8

Glue is published for the nameservers inside the zone: svc-dns-publique-01.ac-normandie.fr, svc-dns-publique-02.ac-normandie.fr.
✓ 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 4 IPv4 /24s and 0 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS2200 (FR-RENATER - Renater, FR): 5 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
!

No IPv6

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

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns0.ac-grenoble.fr: "9.20.15-1~deb13u1-Debian"; svc-dns-publique-01.ac-normandie.fr: "9.18.33"; svc-dns-publique-02.ac-normandie.fr: "9.18.33". 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: dnse1.ac-rennes.fr (195.221.67.4): dial tcp 195.221.67.4:53: i/o timeout.

#19
✓ EDNS supported #20

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

All nameserver addresses are publicly routable.

Serials differ

The nameservers serve different versions of the zone: 2026102618 on svc-dns-publique-01.ac-normandie.fr (193.50.120.71), svc-dns-publique-02.ac-normandie.fr (193.50.120.72); 2026243795 on dns1.ac-lille.fr (194.199.79.6), dnse1.ac-rennes.fr (195.221.67.4), ns0.ac-grenoble.fr (193.54.149.20). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.
