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.
✓ Expires on 2026-12-18 #3

The registration is valid until 2026-12-18 (57 days).

No transfer lock

The domain has no transfer lock (status: active). A registrar lock protects against unauthorized transfers.

#4
✓ Registry and delegation match #5

The nameservers registered at the registry are the ones published in DNS.

2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: sdns01.zzbind.com, sdns02.zzbind.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 one network

all IPv4 addresses are in 46.19.24.0/24; all IPv6 addresses are in 2a02:28c0::/48. 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 (AS51806 (CYIM - CYBER IMAGINATION (CYIM) SASAU, 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 .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
✓ All reachable over IPv6 #13

Every nameserver has an IPv6 address.

Nameservers not responding

These addresses did not answer, so resolvers waste time on timeouts: sdns01.zzbind.com (2a02:28c0:0:ebe1::6f): read udp [2a01:4f8:1c1c:eebf::1]:45851->[2a02:28c0:0:ebe1::6f]:53: i/o timeout; sdns02.zzbind.com (2a02:28c0:0:ebe1::de): read udp [2a01:4f8:1c1c:eebf::1]:47186->[2a02:28c0:0:ebe1::de]:53: i/o timeout.

#14
✓ All authoritative #15

Every responding nameserver answers authoritatively for the zone.
✓ No recursion #16

The nameservers do not answer recursive queries for other domains.
!

Software version disclosed

These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: sdns01.zzbind.com: "9.16.50-Debian"; sdns02.zzbind.com: "9.16.50-Debian". Hide or replace the version string.

#17
✗

Zone transfer allowed

These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: sdns02.zzbind.com (46.19.24.222): 19 records. Restrict zone transfers to your secondary servers.

#18
✓ TCP supported #19

All nameservers answer over TCP.
✓ EDNS supported #20

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

All nameserver addresses are publicly routable.
