They seem to do that pretty well without me explicitly broadcasting my MAC address.

In The Netherlands IP adresses are either static or semi static. The dsl providers issue static addresses. The cable boys issue addresses that are technically dynamic but that do not change unlees the MAC address of the interface is changed or during a _very_ long break. My address has not chaged in five years.

I did not have to change my IPv6 address. Ever.

I know that privacy is very important in Germany. I wish we had the same attitude here in The Netherlands. But I do not see how changing the IPv6 prefix is going to do much good to protect privacy. It seems like an execise in futility. One might as well argue that the number on your car should change every six month to protect privacy.

MR> I fully agree. The best approach would be to set dynamic prefixes as MR> default and let the customer change that to static if he likes to.
That would be an option.
MvdV>> AFAIK, the Dutch IPSs that offer native IPv6 all issue static MvdV>> prefixes.
Although that may change as well. Ziggo is rolling out IPv6 now. Since 14 September new customers get native IPv6 with ds-lite. It is too early to tell if the IPv6 prefixes they offer are static.
