Still lots of dark areas [1] and lots of unnecessary allocated space to original adopters. I wonder if the Governments will ever exercise an Eminent Domain on IPv4 one day?
A lot of those early adopters are self explanatory but how did Ford end up with an entire /8? Merck and Eli Lilly? Prudential?
They asked for it and at that time you didn’t really need to justify it.
There is no government control on IP address space. The only actual binding is to the 5 RIRs*, and if you want to see how eminent domain would fare there... Take a look at the current AfriNIC situation :(
