Checks

  • ✓ 3 nameservers #6
    Delegated to nsgbr.comlaude.co.uk, nssui.comlaude.ch, nsusa.comlaude.net.
  • ✓ 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 2 IPv4 /24s and 2 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS62597 (NSONE - NSONE 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
  • ✓ Nameserver names under 3 TLDs #12
    Nameserver names use the TLDs .ch, .net, .uk.
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
