Geoff Huston recently released his 2015 report on IP addressing. Here are a few notes from the larger report.
- AfriNIC is the only RIR which continues to have an IPv4 free pool available
- ARIN exhausted its free pool in mid-2015 and is now only allocating small blocks from an IPv6 transition pool
- IPv4 transfers continue to increase with 3,643 transfers recorded in 2015 which is more than double from 2014
- The volume of IPv4 transfers almost tripled in 2015 to 58,309,888 IPv4 addresses
- Carrier-grade NAT (CGN) and other NAT applications continue to dampen the real demand for IPv4 addresses
- IPv6 allocations continue to hold steady with 4,733 allocations made in 2015
