excuse top posting - I don't see a case for shifting 240/4 into public IP space if it is just going to sustain the rentier sinecures of the existing IPv4 incumbencies. In other words if RIRs don't use it boost new entrants it will just add another knot to the stranglehold we are in vis IPv4. I can see a potential case for shifting it from experimental to private space given the fact that "the rest of us" without public IP space and natted behind CGNATs have taken to use IPv4 for wireguard, containers, zero configs and so on, to tie our various locations, services and applications together within our own private distributed nets and expose our services for public consumption over IPv6.

Hi Denis,
It will only be burned through if RIR communities change policies to allow for larger delegations than what is currently in place. I believe that some level of change is possible whilst limiting the exhaustion rate, e.g. allowing for delegations up to a maximum holding of a /22, however we shouldn't go crazy (for want of a better phrase) and allow for delegations of a /20, /19 etc.
If this was only going to give us a potential 1-3 years' worth of space, then I would agree in saying that it is a waste of time, would take far too long to make the space usable and wouldn't be worth it. However, as long as we don't get greedy, change the maximum allowed delegation to large delegations, and every Tom/Dick/Harry applying for a /16 allocation then 240/4 will last us a lengthy amount of time, at least a few decades.

This doesn’t seem all that positive to me, particularly because it’s temporary since the underlying problem (limited resource, unlimited demand) cannot be addressed.
I agree with this. Yet I am in favor of changing the status of 240/4, just so it can get burned fast, we stop this endless discussion and can start to deploy IPv6 again.
