>What you propose is perfectly workable, but I don't >see how it's *better* than what DHCP already provides. My belief is that one of the benefits of IPv6 is that it does automatic address allocation without needing a DHCP server. This is good. This means that your network operations people have one less server to install and configure and maintain. If we make our IPv6 hosts dependent on DHCPv6 servers for lots of critical information that they cannot operate without, then we still need to run a DHCP server and we have lost that IPv6 benefit. Since (a) hosts still need to find out information like "Where's my time server", and (b) in an all-IPv6 world we still plan to run DNS servers anyway, then if we can put information (a) into DNS (b), we can eliminate the burden of also having to install and configure and maintain a DHCP server. Instead of having to communicate arbitrary bootstrap configuration information to hosts, we now just have to communicate the name server address(es) and the default domain, which is a nice simple constrained problem that can be solved in any number of simple ways -- e.g. add that information to Router Advertisement packets. [Of course, I am well aware that this point of view will not be popular with all the people working so hard for so long on DHCPv6. Also, if you have a company that sells a DHCP server, then eliminating the need for DHCP servers is not in your company's best interest.
