2019 Addressing

Geoff Huston has posted his annual review of the addressing world. Here are a few of my notes from reviewing the addressing and BGP reports.

  • IPv4 transfer transactions continued to grow in 2019, but the volume of addresses transferred fell to just over 44 million from highs in 2017 & 2018.
  • In the past 24 months the number of unadvertised /8s has actually risen from the 44-45 range to close to 50. This would seem to indicate that possibly the largest blocks have stopped being routed, and were transferred to other entities, but were not readvertised to the public Internet, yet, or that they are now being used internally for some purpose.
  • IPv4 blocks which are transferred are being broken up into smaller blocks in the ratio of approximately 9.5:1. That is for every original block which is transferred and broken up into smaller blocks 9.5 new blocks are created from the original.
  • US to US transfer transactions continue to dominate the transfer market with about 30 million of the 44 million in transfers in 2019.
