Every now and again, you have to rebuild the Internet from scratch. That's what began in earnest in 2012, as many Net powers powered up their sites on a next-gen network technology called IPv6 that's got vastly more room for individual devices than the current IPv4 that's been used since the Internet began.

With the world running out of IPv4 Internet addresses , network engineers have to use various tricks to accommodate all the new mobile phones, PCs, and servers joining the Net every day. IPv6 makes room for them and for all the Internet-enabled fire alarms, pet collars, car computers, talking toys, vending machines, and bloodstream nanobots.
