I'm also wondering about sockets in listen() on less-than-any interface(s), bind() seems to work on IP-Addresses, not interfaces. I have a copy Steven's Unix Network Programming (a Volume 1 second edition that I purchase while at the Pittsburgh IETF in Aug 2000) I don't see (IPv6) "renumbering" in the Index or Table of Contents, is it somewhere describe for apps programmers how to deal with renumbering events? Or is it a "Reboot for changes to take effect" type of activity? -Martin
