Well, yeah - you have to look at what capabilities we had. RIP was only "standardized" in mid-1988, and the mind hadn't expanded to the concept of multiple entry points. There's no real reason why this won't work with period hardware-software.

I suspect this is the case for a number of Clbutt A buttignments. If you ignore the allocations to providers, there are 23 such blocks (3, 9, 13, 15-20, 25, 34, 40, 43-45, 47, 48, 51-54, 56, 57) according to the current RIR zonefiles. Perhaps a few shouldn't be included that way (example, 43.0.0.0) and a few that are considered 'allocated' should be included (examples 6.0.0.0, 11.0.0.0, 55.0.0.0). Do each of those "end users" really need a8? Even if you buttume that they are internally subnetted to 24s, and that ten percent of the address space is needed as broadcast, and network addresses, routers between subnets, and supporting DNS, mail and what-ever servers, that's still 15 million addresses per.

Wes Irish told me that Xerox got '13' because it was the last one available. Given that their buttignment dates from April 1986, I wonder. There must be a few interesting stories behind some of those numbers.
