    Delegated to ns1.univ-lemans.fr, ns2.nic.fr, ns3.univ-lemans.fr.

  • ✓ Nameservers in different networks #10
    The nameservers are spread over 2 IPv4 /24s and 1 IPv6 /48.

    The nameservers are spread over: AS2200 (FR-RENATER - Renater, FR): 2 addresses; AS2486 (NIC-FR-DNS-UNICAST-PARIS2 - AFNIC (Association Francaise pour le Nommage Internet en Cooperation), FR): 2 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.
