   =7C A program that really wants to use the same socket for both *must*
   =7C set ipv6only to 0 via the appropiate setsockopt call.
 
 Either that or:
 	sysctl -w net.inet6.ip6.v6only=3D0
 
 which it is possible that Joel has in NetBSD 7 but not in NetBSD 6
 
 But Joerg is correct, this has never been the NetBSD default.
