There are, however, technical reasons why ISPs might want to use dynamic IPs
(if they have lots of dial-up hardware in different locations, routing
issues make static IP difficult), so although their customers would get a
/64, it might be a different one every time they dial up.

In that situation, since I wouldn't want addresses on my local network to
keep changing, I would want to use NAT to translate the address block
assigned by the ISP onto some site local address space.
