Geoff Huston recently released his annual addressing report looking back at 2016. Within his report a few things jumped out at me.
- Transfers (almost 4,000 transfers constituting more that 32 million IPv4 addresses) continue to grow and mostly are old legacy address blocks which are now being put into reuse.
- The ARIN region, despite its restrictive “need-based” policies on IPv4 transfers continues to lead in transfers with more than 15 million addresses in 2016.
- Transfers are creating some level of deaggregation, this was largely expected as current IPv4 address holders break up larger blocks to sell either for a higher per unit price, or to match the size needed to buyers.
- The number of IPv6 addresses being distributed to organizations continues to increase with more than 50,000 /32s being distributed in 2016.
