ARIN Down to Final /8 of IPv4 Addresses

Now in April of 2014, ARIN (American Registry for Internet Numbers) is announcing that it is down to the final /8 of available space in its own inventory. ARIN manages IP address space allocations for the U.S., Canada and Caribbean regions. ARIN is one of five global Regional Internet Registry (RIR) organizations that in turn receive their IP allocations from the Internet Assigned Numbers Authority (IANA).

“ARIN may experience situations where it can no longer fulfill qualifying IPv4 requests due to a lack of inventory of the desired block size,” Leslie Nobile, director, Registration Services at ARIN, wrote in a statement.

Each IPv4 /8 block contains 16,777,214 addresses. ARIN is now down to its final /8 allocation. ARIN can choose to give out IPv4 allocations in smaller blocks, which include a /10 allocation of 4 million addresses or a /15 allocation of 131,000 addresses.
