First, thanks for taking the time to reply. That is appreciated. With the op hat on...... I want to dual-stack DHCP with complete feature parity, and it be done with one DHCP server. The only thing I should, speaking as an operator, have to do is add the IPv6 stanzas to the working v4 config, restart, and dualstack DHCP Just Works. If I have to hack the code myself to do it..... (and, while I might not, someone will, standards or no standards.

As long as there's a dual stack, the vectors for v4 will work against the v4 portion of the stack. So, no, it ends up adding things to an already crowded plate. > I did this for routing.

Now, taking the op hat off for a moment, and stepping down from the soapbox, this is something that could be useful; has this talk been recorded and/or transcribed? If so, that's a useful resource, and, an hour and a half of relevant material is much easier to swallow than some of the books out there. If a book like Geoff Huston's excellent 'ISP Survival Guide' but for IPv6 (Hey, Geoff, is there an IPv6 version of your book?) were out there..... I know my 1999 edition of that book has seen plenty of use, mostly by people I loaned it out to when they asked me 'how does this thing called the Internet work?' A point-by-point "here's how you do in v6 that you're doing in v4" and "how to overlay your v6 subnets on RFC1918 NATted addresses without forklift upgrades in 12 easy steps" you might have an audience, as long as the first line of the book isn't "Everything you know is wrong." Even papers on how to rework your IPv4 network to more easily transition to dual-stack would be helpful (and those are probably out there; anybody got a cluepon page set up yet for those resources?) > There are some good books on running IPv6, you know. :-) I know. My book budget got cut almost completely out last year, as well as the budget for more bookshelves and floor space, so I'll have to finance those by selling off old ones. Anybody want a CiscoPress ATM book or ten? :-)
