I'm still waiting for the IETF to come around to allowing feature parity between IPv4 and IPv6 when it comes to DHCP.
And that recent thread on prefix delegation doesn't really leave a good taste in one's mouth about how to delegate a /56 or a /48 to a CPE, and get that/those prefix(s) in your (ISP) routing tables. Given that 99.999% of home users would be fine with a delegation of a single /64 and a single subnet I'm tempted to do that for now and let the DHCP-PD ink dry for a while so CPE support can follow up.
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
