Currently with v4 I have one (majority) of customers where they have dynamic addresses. For those I'm happy to use PD - but my point was that people are starting to assume that v6 WILL mean static allocations for all customers. This is my fear, is NOT being able to use PD for the "residential grade" customers. Having to provide static allocations is a problem if I have multiple POPs in a geographic region as I can't summarise and get the redundancy I want.
Summary of IPv6 is easy enough, and you'll probably assign at least two /48 networks to a pop, one for infrastructure and one for PD. I'm sure there will be more.
(If I commit to a customer they have a static range then I can't easily change it on them - esp if they've done things like used the addresses statically in DNS etc as our customers are want to do).
There is a difference between static assignments to an interface for technical reasons and giving a customer a "static". Even if the customer technically has a static address, you are still allowed to change it so long as you are not giving him a static address. It's just a long term dynamic prefix. Renumbering IPv6 is a cake walk compared to IPv4, as it is somewhat more friendly to existing connections than IPv4 (if using stateless autoconfig).
Has anyone out there actually done an implentation, across DSL of PD? If you have PLEASE let me know on list/off list/by dead letter drop in a park. Especially interested in CPE etc.
Cable is much further along on CPE than most home routers. Outside of the Apple Airport, I think there's only a handful of CPE home routers with v6 capabilities.
Here's someone's experience with a real home v6 implementation from ISP side to home router. http://geekmerc.livejournal.com/699.html
