Why is delegating smaller addresses impossible? Kernels will totally take /72, /88, /96, etc. without issue... or at least any OS I've ever used will.

- kllrnohj 2y agoIt breaks SLAAC so routers won't do it. Or if they do, it's non-standard and they won't easily let you do it. /64 is the smallest PD by spec ( RFC 5375 )
- api 2y agoYou can do it with DHCPv6, but of course there's Android. Android aside, it works fine. The core of V6 -- longer IPs -- is great. SLAAC and /64 being the smallest need to be deprecated. It's asinine. Really absolutely everything but longer IPs should be deprecated and was a mistake.

Android aside, it works fine. are you sure? what about homepods, Chromecasts, Hue bridges, kasa smart plugs, esphome, etc etc etc...? How much are you willing to bet your home network on Android being the final user of SLAAC? And how much time do you want to invest in figuring that out in the first place?
- quuxberlin 2y agoIt may brake SLAAC. OpenBSD implements autoconfiguration for non /64 prefixes (IIRC)
