The cable ISP that I had (prior to moving) assigned a single /64 for the 
outside of the router.  I could also request provider delegation for 
something that I could use internally breaking into multiple /64s.  I 
just don't remember if it was a /56 or /60.

The point being that the outside of the SOHO router and the inside PD 
were two different DHCP processes, both of which needed to happen.
