    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: hermes.vgc.be (glue 195.244.180.3, zone 91.183.140.230). Update the glue at your registrar.
    #8
  • ✓ 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 0 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS15383 (UNSPECIFIED - Paradigm, BE): 4 addresses; AS5432 (PROXIMUS-ISP-AS - Proximus NV, BE): 1 address.
  • i
    All nameserver names under .be
    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.

  • ✓ No CNAME at the apex #33
    The zone apex has no CNAME record.
