My talk's slides and video at netdev 0x13 about

"Potential IPv4 Unicast expansions" is up, here: 

https://netdevconf.org/0x13/session.html?talk-ipv4-unicast-expansions

There are roughly 419 million IPv4 addresses that are unallocated and
unused in the 0, localhost, reserved future multicast, and 240/4
spaces.

Linux already supports 240/4 fully. SDN's such as AWS already support
the entire IPv4 address space as a unicast playground.

This first patch for 0/8 is intended primarily as a conversation
starter - arguably we should rename the function across 22 fairly
"hot" files - but:

Should Linux treat these ranges as policy, and no longer enforce via
mechanism?

A full patchset for the remainder of the address spaces is on github:
https://github.com/dtaht/unicast-extensions

with the very few needed patches for routing daemons and BSD also
available there.
