There was no misjudgement. IPv4 addresses are still running out. Adoption of IPv6 has helped the issue. Some parts of the world are aggressively going IPv6 only. IPv6 adoption has seen a massive uptick in the last year. Check the google graphs. Also some under-utilized IPv4 address blocks have been recently re-claimed.

> MIT recently sold off half of its class A to Amazon: And garbage like this is why I cannot wait for the IPv6-only future, CIDR let us stall IPv4 address exhaustion but it has caused severe bloating in routing tables. Considering an IPv6 route at the internet level is capped at 64-bits (the max length of a proper network prefix, you can technically do smaller ones but WHY, and nobody will take your BGP advertisement for it either) I expect even with a 2X increase in size occupied by each individual route the size of a full BGP table is going to be dramatically smaller.
