I took my first college network engineering class in the fall of 2000. The professor was retired from the profession and nearly retired as a professor, but so excited about how this cool new thing that was coming. “IP addresses are running out. Imagine an addressing system capable of generating a unique address for every blade of grass on the planet. In a few years you’ll need to learn this new system” I’m sure he’s passed on by now. And I’m sure IPV4 will outlive me.
0-40 km/h (25 mi/h) in 42 seconds…. That’s 42, not 4.2 in case someone thought I missed the decimal. How did this sell almost 92k units per year up through the 80s?
