Checks

  • ✓ 4 nameservers #6
    Delegated to ns1.wordpress.com, ns2.wordpress.com, ns3.wordpress.com, ns4.wordpress.com.
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns4.wordpress.com. ns1.wordpress.com, ns2.wordpress.com, ns3.wordpress.com, ns4.wordpress.com report NS ns1.wordpress.com ns2.wordpress.com ns3.wordpress.com.
    #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 4 IPv4 /24s and 2 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS2635 (AUTOMATTIC - Automattic, Inc, US): 8 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
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
