Geoff Huston has posted his annual IP addressing update. Here are a few things I found interesting in his report for this year.
- The current IPv4 Internet likely has 20 Billion devices connected to just 2 Billion IPv4 identifiers via NAT
- IPv4 transfer transactions continue to increase, 9220 in 2018 vs 6182 in 2017
- The IPv4 transfer volume hit a record in 2018 with 290M records being transferred, the previous highest year was 153M in 2015
- IPv4 addresses that were originally allocated many years ago dominated the IPv4 transfer market in 2018, the original blocks were split into an average of 8 different blocks through the transfer process
- The vast majority of all transfers which occurred in 2018 were between US organizations composing of some 262M IPv4 addresses
- IPv6 allocation volumes increased in 2018 to an all time high of 39k /32 equivalents
