Ah hence the "great bind doesn't work right" email debate last month. (it wasn't a flame, it was very constructive). Am I guaranteed that the first item in the res linked list will be the IPv6 address? If the list is random, then I'll randomly bind to a IPv4 or IPv6 address depending on how the library feels. > Someone correct me if I'm wrong, but I think this different behaviour of > bind() is the current showstopper for writing portable IPv6 applications. It seems that way.
