My take is doing anything isn’t necessary. Two reasons: 1) We aren’t close to running out. The registry shows: 143-252 Unassigned That a lot of room in the registry given the current assignment rate. 2) The second reason is that I think the reason for few IANA allocation requests in this registry is that it is likely that packets containing any new assignments will be blocked in firewalls and middle boxes. It’s hard to get a new protocol deployed. I am doubtful this will change anytime soon. I suspect we will never run out, unless the Internet changes significantly.
I'm always amused, and a bit concerned, by the assumption that the Internet will not change significantly. From my perspective, the Internet seems to constantly change. Not long ago it was hard to imagine any new transport protocol getting much traction, for example. And the tussles between the application writers and enterprise network operators haven't gone away.
