Hey, A quick math what a /24 can give you if you use if for translation/transition purposes only (NAT64 or A+P like MAP-E/T) If you connect to your upstream with *their* IP addresses and not break your /24 into smaller bits and connect your NAT64 or A+P PRR box directly to that BGP router, use first usable address as a gateway, second address as an interface address for your translation/transition box, then you are left with 252 usable addresses for your purpose. That means 65.535 ports per address, giving you 16.514.820 usable ports. Usually sane people predicts between 700 and 1000 ports per user, and that gives you between 16.514 and 23.592 possible users that you can serve at the same time and connect them to legacy IPv4 world. Now everyone will have to figure out if that's enough or not. :) Cheers, Jan
