I already had a global option in my named.conf as
query-source address 10.1.2.4; // Not the actual ip address.
Which sets the address, not the port.
Which was working fine, but I noticed the IPv6 UDP client port was still
using INADDR_ADDY (*), so I tried adding
query-source-v6 address { none; };
right after the existing query-source and it reported an unexpected
token. I'm using BIND 9.3.1 which does include query-source-v6 in the
man page. I've resorted to adding the -4 command line option, so I
guess I've accomplished what I was after, but am curious if the
"query-source-v6 address" works, what would be the proper syntax for
it. I haven't found any examples.
query-source-v6 is similar to query-source except it take IPv6
addresses rather than IPv4 addresses.
e.g.
query-source-v6 address ::1 port 53;
query-source-v6 [address <ipv6] [ port <number];
