Here's one way to look at it: Imagine 1 trillion Bill Gateses standing in a circle (not a pretty picture, but play along for a moment). Now ask each one to convert his fortune into pennies and toss them in a collective pile. If each penny contained 1 trillion tiny computers and each computer had its own IP address, you'd still have used only a fraction of IPv6's potential space. Link
