Hi all, I've reviewed this document and my comments are as follows.
1. Introduction "giving out an excessive". I think we need to define excessive and/or say if this is an objective or subjective perception. A general comment/opinion. I don't think this document should be published as is, because it provides a bad message to the market about IPv6 assignment recommendations not being stable. I will be in favor of a "smaller" revision of RFC3177, not so much disruptive as this one, but in the other way around, discouraging /128 and /64 assignments. I think the motivations behind the /48 are still valid and one of the main goals of IPv6 addressing space is to ensure enough space to end-users, which is only ensured with a clear boundary recommendation. Furthermore, the lack of a clear boundary disrupts the RFC3177 goal of ensuring a consistent subnet to facilitate management and renumbering. In practice receiving a new assignment from and ISP w/o a specific recommendation will be a big source of troubles if different ISPs decide to do different things. Take the case of a user moving from an existing ISP with today provides a /48 to a new one. In addition, as an end user, it provides a recommendation to ISPs to provide a reduced service in terms of the number of subnets, instead of the actual /48 recommendations (with a clear example for /56), which I think is very bad, especially when it is based in a subjective view of "excessive". I also think that the lack of clarity in stating that more than a single /64 is required in most of the cases is going to be wrongly taken as a "go for /64".
