I try to understand DNS64 and there is a problem I don't get. I have
BIND configured with:
dns64 2001:db8:1:64::/96 { // Network-Specific Prefix
clients { me; };
};
and it works, synthesis happens when the domain name has no AAAA records:
% dig +cd @localhost -p 9053 AAAA twitter.com
...
;; ANSWER SECTION:
twitter.com. 30 IN AAAA 2001:db8:1:64::c710:9c66
twitter.com. 30 IN AAAA 2001:db8:1:64::c710:9cc6
twitter.com. 30 IN AAAA 2001:db8:1:64::c710:9c06
I try it now on the new ipv4only.arpa, which has only A and not AAAA
and nothing happens:
% dig +cd @localhost -p 9053 AAAA ipv4only.arpa
; <<>> DiG 9.8.4-rpz2+rl005.12-P1 <<>> +cd @localhost -p 9053 AAAA ipv4only.arpa
; (1 server found)
