 MV> Hello Binkd Team,

 MV> Recently we have seen IPv6 nodes that use 6to4 tunneling for their
 MV> IPv6 internet connection.

 MV> Most OSs default to IPv4 when the destination IPv6 is a 6to4 address
 MV> (2002::/16) and IPv4 is available. There are good reasons for that,
 MV> 6to4 is notoriously unreliable.

 MV> Nevertheless, the IPv6 fans among us like to make IPv6 connections
 MV> with these nodes. Binkd offers the -6 option in the NODE statemant in
 MV> binkd's config. That works. It forces an IPv6 connect.

 MV> But... It is a "hard force", the -6 option only tries IPv6. Without
 MV> the -6 option IPv4 is tried when IPv6 fails, but with the -6 option
 MV> ONLY IPv6 is tried. So when the tunnel fails, one can not make a
 MV> connect.

 MV> I therefore request that the following "soft force" options are added
 MV> in addition to the -6 and -4 options:


 MV> -64   Binkd ignores the OS preference and tries to first make an IPv6
 MV>       connect. If that fails, it tries an IPv4 connect.

 MV> -46   Binkd ignores the OS preference and tries to first make an IPv4
 MV>       connect. If that fails, it tries an IPv6 connect.


 MV> Thank you.

 MV> Cheers, Michiel
