How dynamic is a dynamic IPv6 address?

How dynamic will dynamic addresses be under IPv6? IPv4 addresses, with most ISP's, change relatively rarely. Once or twice a year is not atypical, and sometimes they go for much longer. The impression I get is that most of the need to renumber is driven by technological needs, either the subnet sizes and need to use all addresses in a block, or the combining and splitting of "segments" (channels, etc) on the cable infrastructure. With a /64 on each segment the former goes away. Subnet size will never dictate renumbering. The segments issue could keep driving it, but it's not hard to imagine a world where your router gets a dynamic IP out of a /64, and then does DHCP-PD to get your home block. This block may in fact never need to change. Basically, in IPv6, even if addresses are assigned "dynamically" (really automatically) won't the consumer pretty much always have the same address for the lifetime of their service, for the majority of consumers? -- Leo Bicknell - bicknell () ufp org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/
