  • ✗
    No DNS over TCP
    Nameservers · 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]:35844->[2408:4005:3dc:af00:a6be:339e:a1a0:d2b8]:53: i/o timeout; dns8.51dns.top (219.138.102.210): dial tcp 219.138.102.210:53: i/o timeout; dns8.51dns.top (2408:4005:3dc:af00:a6be:339e:a1a0:d2b8): read tcp [2a01:4f8:1c1c:eebf::1]:35848->[2408:4005:3dc:af00:a6be:339e:a1a0:d2b8]:53: i/o timeout.

    Glue differs from the zone
    Delegation · The addresses at the parent (glue) differ from the addresses in the zone: dns7.4cun.com (glue 240e:d9:c200:300::36, 61.172.183.74, zone 61.172.183.74, 2408:4005:3dc:af00:a6be:339e:a1a0:d2b8). Update the glue at your registrar.

  • !
    No EDNS
    Nameservers · These nameservers don't support EDNS(0), needed for DNSSEC and answers larger than 512 bytes: dns7.4cun.com (61.172.183.74), dns8.51dns.top (219.138.102.210).
    #20
  • !
    Not signed
    DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.
