I can't speak for all operators, but I would say most I have dealt with do not specifically suggest that a single /64 is the target. That said, there are current operation considerations which factors into the present Wireless and Wireline network prefix assignments. This has caused situations where a single /64 is given out or made available for now. In the longer term, I would think that shorter prefixes would be handed out. There is no guarantee how large of a prefix will be provided - This is likely an operator to operator decision (but market demand normally dictates the eventual outcome). > >I don't hold out much hope that much of a market will ever exist for >residential networks with multiple subnets per subscriber.

I don't agree that operators are not considering multi-subenet home networks. I know of at least one which is looking at more. As for co-ordination between operators, I suspect this is subject to traditional behaviours (no reason to assume character will change for IPv6) > >That's why it looks to me like HOMENET will eventually converge on >specifying single /64 links behind a single residential gateway. I personally would not like to see HOMENET confine the work to a single /64. I do however think the group needs to consider the fact that a gateway MAY get a /64 (a sad, but perfectly valid PD) for any number of reasons- therefore it needs to be considered in how the HOMENET treats the situation.
