The standard size assignment to an end user is /48 per IETF recommendation. That's 65,000 LANs, 2^80 IP addresses. Vanishingly few end-user organizations actually have a need for more LANs than that. However, since /48 is also the minimum Internet routable size, end-user organizations with multiple independently-connected sites may need several /48s. That's a minority of end-users but still a significant number. This is all true; However, justifying a larger end-user allocation (formerly known as an assignment) isn’t that hard either; you justify a /48 per site in a larger multi-site organization; they don’t have to be independently connected. That is, more than 1 site but less than or equal to 12 sites receive a /44 allocation; more than 12 but less than or equal to 192 sites receive a /40 allocation; see the policy for even larger allocations and a discussion for campus environments. Also, most larger organizations likely could qualify as an ISP/LIR if they wish. So, many end-user organizations are receiving /44s, /40s, and even larger allocations without much trouble. Could the ARIN staff provide an updated histogram of IPv6 allocation sizes; I haven't seen one in several years. I hope that helps. ISPs get a /32 so that, by default, they can assign 65,000 /48s to their customers and still keep a few for themselves. That's the reason they receive significantly more.
