Nameservers not responding

These addresses did not answer, so resolvers waste time on timeouts: ns.internlnet.nl (31.3.105.132): read udp 46.225.38.91:47117->31.3.105.132:53: i/o timeout.

These nameservers answer version queries with a string that is not a version number: ns.internlnet.nl: "Served by PowerDNS - https://www.powerdns.com/"; ns3.internl.net: "Served by PowerDNS - https://www.powerdns.com/"; ns4.internl.net: "Served by PowerDNS - https://www.powerdns.com/".

#17
✓ Zone transfers refused #18

No nameserver allows a zone transfer to the public.
