As I said, things are different with DHCPv6. In particular, although you *can* distribute global addresses with DHCPv6, I wouldn't necessarily recommend that you do so. It's a little annoying to administer, and doesn't really add a whole lot of value over the standard choices of stateless autoconf (for most clients) or static (for most servers). Notably, prefixes (aka "netmasks") are not provided by DHCPv6, but instead by RAs. If a DHCPv6 server gives out an address, it's just a bare address with no prefix length. That makes it quite a bit different from IPv4 DHCP, because it means that you have to make sure that the advertised prefixes (in "the" router's RAs) always line up with the address pools on the DHCPv6 server. And there's really no mechanism to do this other than the administrator's fingers and short-term memory. ;-} In a well-managed and large network, I can certainly see a good bit of value in a DHCPv6 server to make sure that everyone has the right name server addresses and such, and to centralize the management of "static" IP addresses.

As I said, I haven't kept up. I've been using IPv6 on my home network for many years (with a tunnel to Hurricane Electric), and haven't really had a need yet to set up a DHCP server, so it's not a question I've tried to answer. -- James Carlson 42.703N 71.076W <carls...@workingcode.com> _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
