One is that it does IPv6 first (I suspect IPv6 wasn't enabled by default on 7.x?). The other is the port randomization code, which probably results in more frequent collisions with port #s used by other things. (Basically, the code selects an unused port# for either UDP or TCP over IPv6 (I can't remember which comes first:-) and then expects that port to be available for the other 3 combinations of UDP/TCP x IPv6/IPv4. rick
