No, but it is the best option and it's allocation and use will lower the pain inflicted by CGN on the Internet at large. > - What is the effect of burning 4 million IPv4 addresses on the exhaustion of IPv4? The benefit of a shared space far outweighs one months worth of addresses for one RIR. Plus, it is likely that the availability of a shared CGN space will slow allocations enough to offset this one month loss. > - Can alternative /10s be used? This has been stated many times already (and is contained in multiple drafts), so I'll just leave a high-level summary of our other options as a reminder: - RFC 1918 space WILL NOT be used by operators. - Globally unique space is a waste and has all the same problems as a shared /10 with the added problem of lack of standardization. - Squat space has all the same issues as a shared CGN space plus the lack of standardization plus add the complications of squatting. - 240 - All the same issues of a shared CGN space but add the complications from an explicit/intentional lack of vendor support in many of the devices in question. > By contrast, further discussion of the following topics would not help the IESG gauge consensus: <snip> Agreed. The bottom line here is that if we remove ourselves from the religious/political debate and focus on operational realities - the choice is not a hard one. The allocation of a shared CGN space is the best thing we can do for the Internet, it's users, it's operators, it's vendors, and for IPv6 deployment as well (which is actually redundant).
