> enhance IPv4 by adding more digits I mean, that's not too far off from what IPv6 is. The main difference, at least as far as the visual addresses go, is that IPv6 also supports letters, which drastically increases the total number of addresses beyond what extending the number of characters would do. I think part of the idea was that, since transitioning from IPv4 to IPv6 is going to be difficult, we might as well make it worthwile be ensuring that another transition never needs to happen again for the forseeable future.
