We all know we’re running out of IPv4, the old-style Internet Protocol (IP), addresses). If you’re in the network business, you know you need to start switching over to IPv6 soon. What you may not know though is that you can still buy IPv4 address blocks even if your region is officially out of them.
Recently, the American Registry for Internet Numbers (ARIN) the Regional Internet Registry (RIR) for the US, Canada, and the Caribbean “implemented Policy ARIN-2011-1: ARIN inter-RIR Transfers. This policy creates the opportunity for organizations to move address space between regions and removes boundaries from the growing IPv4 Transfer market.”
