Apologies to those cross-posted on the V6 Tech list: Hi all, I am just putting together a couple of graphs (see attached spreadsheet). comparing historical V4 deployment (currently looking at number of published A records as my metric) to the current v6 deployment. Rather than make a direct comparison of v6 vs v4 AS's etc as in Geoff Hustons reports, I am looking to show that the size of the v6 Internet is roughly equivalent to the size of X historical point in time of the v4 Internet. Currently using the DNS A/AAAA record metrics it looks like the current size of V6 Internet is around the same size of the historical 1998 V4 internet. I know using A/AAAA records isn't the greatest of metrics, but with the point in mind of showing historical comparative sizings is I think useful for showing the need to be engaged actively in deploying V6. Any further suggested approaches and especially data sources for furnishing this investigation appreciated. Kind regards -JoelW
