Which thread on which list? DHCP-PD works to any home gateway that supports IPv6. I know how the routing is set up in cable, don¹t know about other access. Or did you mean a prefix for a mobile device? Ongoing discussion in IETF v6ops, with consensus that multiple addresses are needed. There¹s disagreement among ISPs about what size prefix to delegate. So what? Pick a number and do it. I don¹t know of anybody who thinks a /64 is right for the home user, but I know of clueful people running every nibble between /60 and /48. Pick a number, plan so you can change it later, and deploy. Lee > >Chuck > >
