IPv6 switches on

The internet has been running out of addresses for some time now. Fortunately, IPv6 gives us 10 billion billion billion times as many as we had before. Yup, that’s about 5 X 10 to the 28th power addresses for each of the 6.5 billion people alive today. In practice they won’t all be used, the vast numbers allows more meaningful addresses, specialty address types (like multicast), and other refinements which allow more systematic and efficient routing of network traffic.
