Regarding the 44/8 and IANA:
Please don't "shake the hornets' nest," by asking IANA or ARIN. While IANA issued the /8 when it ran "Internet Registry," it is actually referenced in RFCs. It is a technical fixture of the "DARPA Internet" that the 44/8 addresses are AMPRNET. The legal question of: "is an IP address property, and if so, do legacy IP holders have different property rights than those allocated from RIRs" is a DANGEROUS question to venture into having solved before IPv4 "goes the way" of thrift store dialup modems.
Why? Because of all those who still hold legacy allocations:
AMPRNet is the only one that is: - non-commercial - nonprofit - not part of military-industrial complex - not part of the big-pharmaceutical industry - not governmental - not part of big-telecom - not part of the financial industry - not part one the major corporations, nations or firms that help rebuild/establish/maintain the infrastructure of the globe during/after World War II
What /8 do you think they'll try to take first when the world's number resources approach 0.01 /8's remaining to allocate???
