the kind of do with http://tools.ietf.org/html/draft-arkko-homenet-prefix-assignment-03 but you can't a) expect the ISP routers to be able to discover each other (might not be on the same link), b) operated by the same entity. > I couldn't find specifics on "DHCP option for SAS/DAS policy", so I don't > know what that means exactly.
