[public-dns-discuss] DNS64 Not Resolving Addresses



Erik and team,



The public DNS64 resolvers are pingable but do not resolve. The following simple test is coming from an IPv6-only network that is behind NAT64.

ping6 2001:4860:4860::6464
PING6(56=40+8+8 bytes) 2601:2c3:887f:5f73:11b7:5c86:b051:5c2c --> 2001:4860:4860::6464
16 bytes from 2001:4860:4860::6464, icmp_seq=0 hlim=42 time=133.313 ms
16 bytes from 2001:4860:4860::6464, icmp_seq=1 hlim=42 time=25.670 ms

ping6 2001:4860:4860::64
PING6(56=40+8+8 bytes) 2601:2c3:887f:5f73:11b7:5c86:b051:5c2c --> 2001:4860:4860::64
16 bytes from 2001:4860:4860::64, icmp_seq=0 hlim=44 time=635.711 ms
16 bytes from 2001:4860:4860::64, icmp_seq=3 hlim=44 time=1911.751 ms
16 bytes from 2001:4860:4860::64, icmp_seq=4 hlim=44 time=915.951 ms
16 bytes from 2001:4860:4860::64, icmp_seq=5 hlim=44 time=24.304 ms
16 bytes from 2001:4860:4860::64, icmp_seq=6 hlim=44 time=23.048 ms
