@siguza @jstangroome I think the specs never said what "reserved" means. Until the "future use" is actually defined, are you supposed to drop packets, or accept them and forward them as if they were regular addresses? In hindsight, the former makes it impossible to introduce a new use for it, but... specs didn't say.

@nicolas17 @siguza given the official definition of the IP space, I appreciate it is a reasonable default for routers to drop packets using those IPs to mitigate abuse. Unfortunately whether it's a router firmware update, or a trivial configuration toggle, there are going to be router operators unwilling to make those changes. And then there's the end-of-support router hardware that would need replacing. *Sigh*.
