Checks

  • ✓ 4 nameservers #6
    Delegated to ns1-07.azure-dns.com, ns2-07.azure-dns.net, ns3-07.azure-dns.org, ns4-07.azure-dns.info.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ 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 4 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS8075 (MICROSOFT-CORP-MSN-AS-BLOCK - Microsoft Corporation, 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
  • ✓ Nameserver names under 4 TLDs #12
    Nameserver names use the TLDs .com, .info, .net, .org.
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
