There are several other arguments for dynamic addresses, for instance:

- Dynamic addresses often make it easier to perform bulk moves of large
numbers of customers.

- Dynamic addresses for residential customers is a way to justify higher
cost (and profit) for a "business" type service with static addresses.

Given that many service providers find dynamic addresses for residential
customers extremely convenient, *independent of the number of available
addresses*, is there any reason to believe this will change with IPv6?
