Hi,

Do you mean ::ffff:a.b.c.d type addresses ?  I'm probably 
mis-understanding things.  Can you give me an example of how such a 
connection is supposed to work ?  I mean... if ::ffff:* addresses 
aren't supposed to understand IPv6, why are they a concern ?  I'm 
clearly missing something.

My change was done because the normal IPv6 scenario doesn't work at 
the moment (where I have gw.lan.Awfulhak.org resolving an A request 
to 172.16.0.1 and an AAAA request to fec0::1).  When I connect from 
fec0::1 it simply fails to resolve using AF_UNSPEC and dumps fec0::1 
in utmp :(

Thanks for any light you can put on the subject :I
