DHCPv6-PD isn't a "restriction", it's simply what gets handed out today. A "simple" reconfiguration on the DHCP

for what they need/want; assuming they just default to asking for the largest block they're allowed and using only 3 
networks.)

I find it amusing that people want to argue both that:

- A /56 is horribly wrong and the world will end if we don't fix it NOW.

- Providers could give out more by simply changing a setting on the DHCP server.

I would love to know what number of home users need 256 subnets.  The good news is that folks doing DHCP-PD will be 
able to report on how many people request all 256 networks available, and are thus "out".  In fact they can make a 
histogram from 1 to 256 networks per household, and show us how many request each number of subnets.

I challenge Comcast, AT&T, and others to do just that, and publish it on a regular basis, if only to make people stop 
talking about this "issue".
