Checks

  • ✓ 3 nameservers #6
    Delegated to diego.sigma.fr, manny.sigma.fr, sid.sigma.fr.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: diego.sigma.fr, manny.sigma.fr, sid.sigma.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 3 IPv4 /24s and 2 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS35280 (F5 - F5 Networks SARL, FR): 2 addresses; AS39542 (SIGMA-INFORMATIQUE - SIGMA INFORMATIQUE SAS, FR): 4 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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
