Hello Wilfred,

I fully agree. User applications should follow the OS preference unless
specifically configured to not do so. Which of course normally results in IPv6
first if an IPv6 address is found because all modern OS's default to IPv6
first.

 WV> (Of course you could have options that change the preferrence)

Binkd has such an option. One can override the OS preference on a per node
basis. For a point this may not be all that usefull. I can think of a few
cases. Like the Boss node connecting via a 6to4 tunnel. In that cases some
OS's switch the preference to IPv4 fiorst. Or a Boss node that advertises IPv6
connectivity but does not actually have it. But who would want such a node as
Boss?


Cheers, Michiel
