Described as a “test flight” of IPv6 , today marks the biggest concerted effort by some of the web’s marquee players to turn us all on to the newer, fancier web addressing system. Internet Protocol version 4 has been the template by which we’ve addressed everything connected to the web so far, but that stuff’s now nearing exhaustion, so the future demands a longer, more complex nomenclature to tell our smartphones, tablets, printers, and other webOS devices apart. For end users, June 8th won’t really feel too different from June 7th — this will be a change that occurs mostly behind the scenes and there’s an IPv4 fallback option if you can’t connect in the modern way — but Google does warn that a very limited subset of users may experience connectivity issues as a result. Hit the links below to see how well prepared for the future you are.
