The cowards at IANA need to assign Class E IPv4 space, legacy routers be damned.

There are over 268 million IPv4 addresses that are currently unassigned and "reserved for future use," but a bunch of legacy backhaul can't route it due to assumptions baked into the silicon. Wonder if it'd take longer to replace all of that legacy backbone, or get 99% IPv6 adoption.

I'm looking at you, local ISPs.

@endrift I love that everyone saw "reserved for future use" and thought "oh boy free optimization I surely won't need to worry about these ever"
