Agreed. It doesn’t. However, it does not (currently) lend itself to them doing so with a single IPv6 aggregate prefix. Is there a need or desire to do so?

> Based on the discussion around 2017-5, it appears that the most important thing for accountability is the registration of blocks routed differently or assigned to others, which in this example are other community networks for specific areas unless the Community Network holding the space manages abuse for the smaller Community Networks below it. Since the end users would have a /48 or less, there is no need to register the end users. under the adopted 2017-5, unless they have requested registration.

Really, once they get to the point of providing this level of service, I see no reason (or advantage to them) of not being a regular LIR.

> In the example, Rocky Mountain Spotted IPv6 community network might apply for a /40 from ARIN for $250/year. It could do this, or obtain an allocation from Colorado IPv6 cooperative to use. Instead of operating this entire network itself, it might choose to allow other existing smaller groups to operate parts of the network such as the Ball Mountain community and Mount Lincoln. I have no heartburn with these delegations as long as they are SWIP'ed, so we know who is managing each segment of the overall network.

Sure, but you’ve now got 4 networks crammed into a /40 meaning that each can be no bigger than a /42 and with rational allocation policy, no bigger than a /44, ignoring the fact that one of the networks is named after a disease.

> While some might argue that it is no big deal to become a full LIR and get more space, that space comes at a greater cost which may not be affordable. Many of these groups just manage the network, with the end users providing their own access nodes at their own expense, often using some sort of point to point wireless connectivity.  The amount of "cash" for things such as ARIN fees may in fact be quite limited.

You’re talking about a cooperative of 4 networks having to pay $500 instead of a single network paying $250 (or $100) per year. Under older fee structures, it was a significant hurdle. Under the current fee structure, it’s a lot less of an issue.

> While it is not the "recommended" way to do it, some of these community networks may "find" more space for end users by assigning less than a /48 to most of its end users, assigning that smaller value by default, and only giving a /48 to end users upon a specific request.  This allows more users, without more cost for annual fees.

Here I have real heartburn. I really want to avoid writing policy that provides any incentive to do this if at all possible. Part of ARIN’s mission is to promote the development of the internet. Encouraging ISPs to give out less than a /48 to end users is contrary to that mission IMHO.

I don’t think we are preventing any such thing.
