Hi, just a small reaction to what you have written (in line).

Here it starts. I would say get such a LIR what you have got (to /22 of course). Even by means of multiple /24s. But not blocks smaller than /24, as it would be useless. Maybe let them decide if they would like to wait for whole /22 where there would be less then 4x /24 (in that one case). > > d) The length of the waiting list and other practicalities should be > secondary considerations after these principles above.

Sure, add there the waiting list if needed, but do not change the /22.

This > should be a parameter. I'm strongly agains that. Let's keep there explicitly /24 as the longest routable prefix. Allowing a longer one would give a signal to other RIRs that it is fine with us. That would bring yet another deagregation so more junk in routing tables. I'm not sure that we would all agree on changing our BGP filters to allow that. And if so, someone whom will be given such small pool would have problem with reachability. > > 4b) Consider the possibility, however unlikely, that the RIPE NCC > receives a significant amount of address space to re-distribute.

Would (4) and (5) above do the trick? Then it would be wise to pass a policy that would say that. Like: "IPv4 is considered to be a legacy protocol. RIPE would not provide any allocation/ assignment of IPv4 resources." Or what ever. > > 5) Maybe mention explicitly that one has to be a LIR in good standing to > be on the waiting list. More LIRs on the list means smaller chance that anyone would get an address pool. So let them wait there, it just as easely may work as a motivation torward IPv6. Like: "Just look at that list! IPv4 is gone for good." Martin
