I don't understand this analysis. First of all, in the USA McDonalds
has only 12,300 locations. Secondly, according to the existing IPv6
policy, if McDonalds were to go to an ISP and ask for IPv6 connectivity
for their network of 12,300 restaurants, the ISP would assign them 12,300
/48 address blocks. That is the policy and if you don't understand why
each location qualifies for a /48 then you need to do some study on the
fundamentals of IPv6 addressing.

We are not discussing end sites here. We are discussing end users, in
other words organizations which may have one or many end sites in their

When you say "internal subnets" are you referring to /64 blocks? If so,
this is irrelevant to the discussion. /64s are only counted in the very
circumstance where an end site needs only a single IPv6 subnetwork. This
unlikely to occur outside of industrial applications.
