My bet is the number needing more that a single /64 will exceed the number needing just a /64. Most phones really need two /64 for tethering and currently there are lots of kludges to work around only one being available. > I would say that the majority of users today and for the future will not > require a /48, but will simply use the allocation given to them by their > upstream. > > Many today do not multi-home and how many SMB customers just use a single > Public IP behind a NAT device? How many would multi-home if it was a standard feature built into all CPE devices? Cable + DSL? Homenet is designing for all home CPE devices to support multi-homing. Plug in CPE from ISP 1 and CPE from ISP 2 and it will just work.
