Having a running RADVD or DHCPv6 server on the router or somewhere else in the LAN does not necessary mean, that the Internet provider offers IPv6 connectivity. Also a temporary situation may change from time to time.
Yes, that is the issue precisely.
Apparently it is not possible a solution like letting the system know it should not use IPv6 on internet, only on the local network.
"ipv6 internet" and "ipv6 local network" are concepts you apply (e.g. by different address ranges), but the network stack does not know about it. Same as for IPv4. (ignoring RFC1918).
Or having the DNS not answering with Ipv6 addresses, even if it finds them.
A DNS server that does not respond to AAAA queries is not really a DNS server.
Oh, yes that would be ugly and introducing timeouts.
Correct would be a answer of "NXDOMAIN" on all AAAA queries for "noipv6" or "onlyipv4" configurations.
Uh no - if your application wants an AAAA address, it is not up to the nameserver to say "well, you can't have it".
