    Glue differs from the zone
    The addresses at the parent (glue) differ from the addresses in the zone: ns1.bigcommerce.com (glue 35.226.211.142, zone 172.64.53.195, 172.64.52.200); ns2.bigcommerce.com (glue 35.238.43.68, zone 172.64.53.195, 172.64.52.200); ns3.bigcommerce.com (glue 35.238.121.104, zone 172.64.52.200, 172.64.53.195). 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 (AS13335 (CLOUDFLARENET - Cloudflare, Inc., US): 6 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.
