Glue differs from the zone

The addresses at the parent (glue) differ from the addresses in the zone: ns1.celeste.fr (glue 83.142.144.247, zone 83.142.144.247, 2001:ab8:100:2::); ns3.celeste.fr (glue 83.142.144.248, zone 83.142.144.248, 2001:ab8:100:3::). Update the glue at your registrar.

#8
✓ All names resolve #9

Every nameserver name has an address and is not an alias.

One address family in one network

all IPv6 addresses are in 2001:ab8:100::/48, while the other address family is spread over several networks.

#10
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS34177 (CELESTE-AS - Celeste SAS, 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.

Partly IPv6

These nameservers have no IPv6 address: ns1.os-net.fr.

✓ All respond #14

All 5 nameserver addresses answered.
✗

Lame delegation

These nameservers don't answer authoritatively for the zone, so resolvers ignore them: ns3.celeste.fr (2001:ab8:100:3::): SERVFAIL, authoritative=false.

#15
✓ 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: ns1.celeste.fr: "9.11.5-P4-5.1+deb10u2-Debian"; ns3.celeste.fr: "9.11.5-P4-5.1+deb10u2-Debian". 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.celeste.fr (2001:ab8:100:3::): .

#19
✓ EDNS supported #20

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

All nameserver addresses are publicly routable.

✓ Serial 2024013002 everywhere #22

All nameservers serve the same version of the zone.

Unusual SOA timers

retry 4h should be shorter than refresh 4h; negative caching TTL (minimum) 2d is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 4h, retry 4h, expire 1000h, negative TTL 2d.

#23
✓ Primary is a public nameserver #24

The primary nameserver ns1.os-net.fr is one of the listed nameservers.
✓ Contact hostmaster@os-net.fr #25

The SOA RNAME hostmaster.os-net.fr means hostmaster@os-net.fr.
✓ Date-based serial #26

The serial 2024013002 follows the YYYYMMDDnn convention (2024-01-30).
