> 2. Comcast only appears to have a /29 and a /28 (2001:558::/29, 2601::/28). That's only 1.5M /48s, and they have about 10x that many customers. They likely can't use /48 plus semantic prefixes, because if ARIN doesn't accept "semantic prefixes" as using space efficiently (and word from ARIN on this thread seems, well, negative on the matter), then they won't be able to get more space from ARIN. That means that there is a fundamental tension between using semantic prefixes and giving more address space to customers.

It also means that Comcast has a dramatically undersized allocation and will most likely be depriving their customers.
