    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: dns3.4cun.com (61.172.183.74): dial tcp 61.172.183.74:53: i/o timeout; dns3.4cun.com (2408:4005:3dc:af00:a6be:339e:a1a0:d2b8): read tcp [2a01:4f8:1c1c:eebf::1]:53314->[2408:4005:3dc:af00:a6be:339e:a1a0:d2b8]:53: i/o timeout; dns4.51dns.top (219.138.102.210): dial tcp 219.138.102.210:53: i/o timeout; dns4.51dns.top (2408:4005:3dc:af00:a6be:339e:a1a0:d2b8): read tcp [2a01:4f8:1c1c:eebf::1]:53328->[2408:4005:3dc:af00:a6be:339e:a1a0:d2b8]:53: i/o timeout.
