I find it hard to believe that "huge" exceeds 65,536, which is how many addresses you get with a /16.

Ha, you better believe it - even /8 would be tight for them. Ultimately, it comes down to segmentation creating a ton of waste and you need segmentation to manage ACLs and things like that

With ipv6 you can just assign every actor a /96 and they get 4 billion IPs to play with
