This is part of a personal commentary on the meetings at the July 2023 meeting of the Internet Engineering Task Force (IETF 117). If you want to know what was presented and the comments at the mic see the IETF 117 meeting archive. The IEPG meets for a couple of…

All the material presented at the meeting can be found at https://ripe83.ripe.net/. Vulnerability Disclosure Responsible Disclosure is a…
