.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 2028-11-29 #3

The registration is valid until 2028-11-29 (769 days).
i

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: dns-01.archimed.fr, dns-02.archimed.fr.

#6
!

NS sets differ

The nameservers at the parent and in the zone should be the same. Only in the zone: srv-dns-01. dns-01.archimed.fr report NS dns-01.archimed.fr dns-02.archimed.fr srv-dns-01.

#7
✓ Glue present and correct #8

Glue is published for the nameservers inside the zone: dns-01.archimed.fr, dns-02.archimed.fr.
✗

Nameserver names don't resolve

These nameservers have no A or AAAA record, so they can't be reached (lame delegation): srv-dns-01.

#9
!

Nameservers in one network

all IPv4 addresses are in 83.145.86.0/24. 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 (AS15557 (LDCOMNET - Societe Francaise Du Radiotelephone - SFR SA, FR): 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 .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: dns-01.archimed.fr, dns-02.archimed.fr.

✗

Nameservers not responding

These addresses did not answer, so resolvers waste time on timeouts: dns-02.archimed.fr (83.145.86.7): read udp 46.225.38.91:43762->83.145.86.7:53: i/o timeout.

#14
✓ All authoritative #15

Every responding nameserver answers authoritatively for the zone.
✗

Open recursion

These nameservers resolve names for anyone, which makes them usable for DNS amplification attacks and cache poisoning: dns-01.archimed.fr (83.145.86.8). Disable recursion on authoritative servers.

#16
✓ No version disclosed #17

The nameservers don't reveal their software version.
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
✓ 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.
