    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: ns1.tranguard.com (glue 192.235.100.51, zone 192.235.100.52); ns2.tranguard.com (glue 192.235.100.52, zone 192.235.101.52); ns3.tranguard.com (glue 192.235.101.51, zone 192.235.100.53); ns4.tranguard.com (glue 192.235.101.52, zone 192.235.101.53). 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 2 IPv4 /24s and 0 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS36086 (TELX-LEGACY - Telx, US): 4 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • i
    All nameserver names under .com
    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.
