[AfriNIC-rpd] RE:AFPUB-2011-v4-003-draft-02 - Limited Out of RegionAllocation of IPv4 Resources - of Legacy Space

[Owen DeLong]

I believe this is from a special class of legacy addresses that occurred
towards the very end of the legacy period.

An experiment was tried where the InterNIC delegated large blocks to ISPs
who subsequently took care of assigning the addresses to their customers.
However, prior to CIDR, these assignments to customers were "portable"
and it was expected that the customer would take them with them, just
as if they had gotten them from InterNIC. Later with the introduction of
CIDR, the concept of non-portable addresses emerged. Non-portable
is what we now expect of all addresses issued by ISPs, but, it was not
always thus.

I don't think this in any way defines the standards of the relationship
between ISPs and InterNIC or ISPs and RIRs with regards to their
receipt of legacy space.
