All IPv6 address assignments are leases. Whether you get the address from a RIR, LIR or ISP. The lease may not be renewed when it next falls due. You may get assigned a different set of addresses at that point. You should plan accordingly.
Exactly the problem,
In the regional ISP I alluded to in my previous message, /56es are assigned to residential DSL customers and are static (they are handed out to the LNS from RADIUS). The link address (IPV6CP + ND/RA) depends on the particular LNS your PPP session lands on, however.
and the reason A) IPv6 is not and will not be a viable option any time soon (soon being before the publication of an IPv6 NAT RFC), and B) why network providers (and other parties who stand to gain financially) are firmly against IPv6 NAT.
In this case there is no religion for or against NAT inherent in the v6 access service being provided. Customers can do what they want with the addresses provided to them. Joe
