LacNIC announced today that they will start processing InterRIR IPv4 address transfers. LACNIC has been in the process of preparing for this for almost a year after the policy proposal LAC-2019-1: IPv4 Resource Transfer Policy (comprehensive) was ratified in June of 2019.
ARIN has announced that its InterRIR transfer policy is compatible with LACNIC’s and thus addresses can now be transferred between the two regions. I expect RIPE and APNIC also be be able to transfer IPv4 addresses to LACNIC shortly.
This leaves AfriNIC as the only region now without an InterRIR transfer policy. Transfer policies continue to be discussed in the region but none has achieved consensus thus far. Three transfer policy drafts are listed as Under Discussion on the AfriNIC Policy Proposals page now in mid-July 2020.
