Hello

long story short: telnet foo on stable/8 will first try connecting via
IPv6, then via IPv4 (foo has A and AAAA records). On stable/9 it's the
other way round.

This trips up my setup, where a bunch of hosts (some behind NAT) can all
talk to each other over their IPv6 addresses (some are tunneled), but
cannot do so via IPv4.

Is this due to changes in bind or the resolver?

Cheers,
Uli
