Could not be checked

Resolving these nameserver names failed: pluton.utt.fr (DNS query for pluton.utt.fr failed: read udp 46.225.38.91:40329->8.8.8.8:53: i/o timeout).

#9
✓ Nameservers in different networks #10

The nameservers are spread over 3 IPv4 /24s and 1 IPv6 /48.
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
i

Partly IPv6

These nameservers have no IPv6 address: deneb.utt.fr, pluton2.utt.fr, uran01.utt.fr.
