The Day the Internet Ran Out of Room

The internet ran out of room fifteen years ago — there was even a ceremony — and you never noticed, because it quietly learned to sublet. Every device online needs an IP address, and in 1981 the internet's design fixed the total at about 4.3 billion — a 32-bit number chosen as a placeholder for what its creators (Vint Cerf and Bob Kahn) understood to be an experiment. This deep dive traces how that "temporary" choice became permanent: the 1983 flag-day cutover, the giveaway of 16-million-address Class A blocks, the 1994 NAT "tourniquet" that quietly became the architecture, the 2011 Miami ceremony where the last addresses were handed out, and why IPv6 — finished in 1998 — still carries only about half of traffic 27 years later. The lesson that rhymes with the 19-inch rack: nothing is more permanent than a temporary fix that works.
