It seems ARIN now has only 2 /8s left. Which means they must announce Phase 3 of their IPv4 Countdown plan now. - https://www.arin.net/resources/request/ipv4_countdown.html
What this means is the long term is that the cheap IPs will be no more, the prices of IPv4 will increase more and more. So the ultracheap LEBs might disappear in the future.
