Checks

  • ✓ 3 nameservers #6
    Delegated to ns1.ext.philips.com, ns2.ext.philips.com, ns3.ext.philips.com.
  • ✓ 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 3 IPv4 /24s and 3 IPv6 /48s.
  • ✓ 2 autonomous systems #11
    The nameservers are spread over: AS2647 (ORANGE-BUSINESS-NAM - Orange Business Communications Technology Limited, IE): 1 address; AS51964 (ORANGE-BUSINESS-SERVICES-IPSN-ASN - ORANGE BUSINESS SERVICES U.S. Inc., US): 5 addresses.
  • 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.
