> Is there a private organization in need of 16 million addresses?

Plenty of mobile phone networks have well over 16 million subscribers, and they typically don't have enough public IPv4 addresses for everyone. This has led to really hacky stuff, like using DOD IP ranges as psuedo-private space, or re-using private IP addresses in different regions (which can't be fun to maintain.)

Some networks have fixed the problem by using NAT64 - forgoing IPv4 altogether internally, and translating to public v4 at the edge. (Works surprisingly well, T-Mobile US has been doing it for the better part of a decade.)
