  • i
    .fr is a country-code TLD (ccTLD)

    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: bievre.univ-paris3.fr, lendit.univ-paris3.fr.
    #6
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only in the zone: shiva.jussieu.fr, soleil.uvsq.fr. bievre.univ-paris3.fr, lendit.univ-paris3.fr, shiva.jussieu.fr, soleil.uvsq.fr report NS bievre.univ-paris3.fr lendit.univ-paris3.fr shiva.jussieu.fr soleil.uvsq.fr.
    #7
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: bievre.univ-paris3.fr, lendit.univ-paris3.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.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS1307 (UNSPECIFIED - Renater, EU): 1 address; AS2200 (FR-RENATER - Renater, FR): 3 addresses.
  • 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.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: MX (1m), NS (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1m; resolvers may use either.
