  • ✓ All respond #14
    All 9 nameserver addresses answered.
  • ✗
    Lame delegation
    These nameservers don't answer authoritatively for the zone, so resolvers ignore them: ns1.namecity.com (62.128.193.35): REFUSED, authoritative=false.

  • ✓ No recursion #16
    The nameservers do not answer recursive queries for other domains.

    The nameservers don't reveal their software version.
  • ✓ Zone transfers refused #18
    No nameserver allows a zone transfer to the public.
  • ✗
    No DNS over TCP
