    Lame delegation
    These nameservers don't answer authoritatively for the zone, so resolvers ignore them: auth111.ns.uu.net (198.6.1.115): REFUSED, authoritative=false; auth120.ns.uu.net (198.6.1.154): REFUSED, authoritative=false.

  • ✓ Zone transfers refused #18
    No nameserver allows a zone transfer to the public.
  • ✗
    No DNS over TCP
    DNS over TCP is required (RFC 7766); without it, large answers such as DNSSEC responses fail. Not answering over TCP: auth111.ns.uu.net (198.6.1.115): ; auth120.ns.uu.net (198.6.1.154): .

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (20s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1d; resolvers may use either.
