Requirements (1)

Lists options we have, we do not need to pick one.
Usage pattern
Static client: PC in home - static address assignment desired.
Roaming client: travelling note PC - dynamic address assignment.
Address space: /48nnn
NEVER do /128, because it will advocate IPv6-to-IPv6 NAT.
Address allocation
Static address allocation (ISP contract paper describes /48)
Static address allocation (some automation, on first time connection?)
Dynamic address allocation
Routing
Static - easy to setup, too many chances for typo.
Dynamic routing protocols - multihome friendly.
