  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns2.x-plose.be; only in the zone: ns2.x-plose.eu. ns1.x-plose.be, ns2.x-plose.be, ns2.x-plose.eu, ns3.x-plose.be report NS ns1.x-plose.be ns2.x-plose.eu ns3.x-plose.be.
    #7
  • ✓ No glue needed #8
    All nameservers are outside the zone, so no glue records are needed.
  • ✓ 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 3 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS14061 (DIGITALOCEAN-ASN - DigitalOcean, LLC, US): 2 addresses; AS59943 (LEVEL27-AS - Level 27 BVBA, BE): 6 addresses.
  • 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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
