✗

Nameservers not responding

These addresses did not answer, so resolvers waste time on timeouts: dns8.51dns.top (219.138.102.210): read udp 46.225.38.91:50624->219.138.102.210:53: i/o timeout.

#17
✓ 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: dns7.4cun.com (61.172.183.74): dial tcp 61.172.183.74:53: i/o timeout; dns7.4cun.com (2408:4005:3dc:af00:a6be:339e:a1a0:d2b8): read tcp [2a01:4f8:1c1c:eebf::1]:54568->[2408:4005:3dc:af00:a6be:339e:a1a0:d2b8]:53: i/o timeout; dns8.51dns.top (2408:4005:3dc:af00:a6be:339e:a1a0:d2b8): read tcp [2a01:4f8:1c1c:eebf::1]:54566->[2408:4005:3dc:af00:a6be:339e:a1a0:d2b8]:53: i/o timeout.
