An operator shows up saying, "we have IPv4 650,000 end users, now give us a /24", or "We have 6,500,000 IPv4 end users, now give us /20" (these are according to HD-ratio 0.8).
Where to get these these address blocks?
There are 2^20 /20's out there - that's 1048576, 10 times as much as we have routes in the IPv4 table right now. So I'd say "giving everybody that can prove to have 6 million IPv4 users a /20 is the right thing to do and NOT wasteful". There are certainly less than 2^20 entities each serving 6 million IPv4 users...
Sure, but this requires significant additional assignments from IANA; 2001::/16 will not be nearly enough. For example, 21xx::/8 might be enough for a while. -- Pekka Savola "Tell me of difficulties surmounted, Netcore Oy not those you stumble over and fall" Systems. Networks.
