[Jool-list] exempting local networks from dns64

https://www.jool.mx/en/dns64.html has an interesting description of
setting up dns64 and it works for Internet host lookups.

What it doesn't do though is account for addresses in the DNS server
for local subnets.

From a host configured to use dns64, a lookup for an AAAA record for a
host on the local network ends up returning the dns64'd IPv4 address
rather than available IPv6 addresses from the local network.

Surely I am not the first person to come across this.  I wonder if
there are any best-known-methods for handling this.  Perhaps the above
web page can be updated to accommodate such a scenario.

Cheers
