My autoconf.fu is nonexistent so I can't help on this. However, the IETF Mafia would prefer if all software supported IPv6 by default, suggesting that if possible the polarity should be SUPPRESS_IPv6 if you really, truly have to. I'm just getting started in this area, but as I understand it, getaddrinfo (3) silently bypasses IPv6 on a host with no IPv6 capability; or if the destination lacks an AAAA record it will provide either native IPv4 address structures or IPv4-in-IPv6 mapped addresses depending on caller flags or on whether it looks like the packet will go out on an IPv6-only interface. About subscriptions: it's easy to join the list, stay on until your thread runs down, then unsubscribe. Alternatively, watch the list archive to pick up replies. With some news readers it's hard to "cc" to an unsubscribed poster. James F.
