I had an ipv6-only lab environment cease being able to browse much of
the internet on Monday. Tracked the issue down to google's public DNS64
service; the following queries should return DNS64 responses from the
64:9bff::/96 prefix, however, I'm getting 0 DNS64 answers from dig on
both their servers for the last 60 hours:
dig @2001:4860:4860::64 ipv4only.arpa AAAA
dig @2001:4860:4860::6464 ipv4only.arpa AAAA
DNS works fine, just not DNS64. A forum topic [0] suggests this
behavior might be intermittent but no official response from google
there. Is google's public DNS64 down for anyone else?
