I want to note that setting the default site to listen is not the behavior I want either.
When I do this, then requests to other sites just hit the default site (which is an empty site).
Basically, the behavior I want is that if I have define IPv6 to listen on a site then that site should be the destination.
However, if I haven't defined IPv6 to listen on a site, then I still want the request to go over IPv4.
I have a feeling I cannot do this while still maintaining my 10 CNAME mappings for one set of A/AAAA records.
I think I will need to create an A record for each site and only create AAAA records for the sites I want IPv6 on?
