This talk is titled "Reducing Internet address waste: The IPv4 unicast extensions project," and was presented at LibrePlanet 2022 by Seth Schoen.

Seth is a consultant living in San Francisco and helped develop the Let's Encrypt certificate authority.

This talk is about the IPv4 Unicast Extensions Project, which is proposing software and standards changes to eventually make reserved addresses usable. Some of our changes have been accepted in systems, including GNU/Linux and FreeBSD. This presentation will describe what has been done and what still needs to happen.
