Re: dynamic or static IPv6 prefixes to residential customers

- Dynamic address: Customer connects PC (defaults to DHCP) or router/ 
firewall with DHCP for the WAN interface plus NAT for the LAN side. 
Necessary configuration: Small to none.

DHCP doesn't imply dynamic address. It implies customer doesn't have to 
configure an address him/herself. DHCP can very well always hand out the 
same address every time.

Absolutely, and in our network it does - in most cases. However, ensuring
that DHCP hands out a *real* static address every time, in the face of non
SP controlled CPEs, changing MAC addresses etc is non-trivial.
