If Google made the same strong statement with IPv6 as they have done with their 700 MHz bid or the Google-subsidized fiber project, it could make a significant difference. A few examples come to mind: - free or discounted advertising to vendors if delivered over IPv6: this would incent advertisers to have viewers access content over IPv6, even if it was just on mobile phones with certain apps. - free or discounted Google Apps if a certain percentage of client access was over IPv6, etc: this would incent enterprises (the non-profits are either free or discounted, so this example applies mostly to the for-profits) to find native IPv6 access because it provides an immediate and direct savings Frank -----Original Message----- From: James Hess [mailto:mysidia@gmail.com] Sent: Saturday, April 03, 2010 1:08 PM To: George Bonser Cc: nanog@nanog.org Subject: Re: legacy /8 <snip> I suppose if Google announced tomorrow, that search engine access over IPv4 is going to be discontinued in 12 months, and you will have to connect using IPv6, then IPv4 might become legacy....... They could have posted that on April 1, with impunity too :) Enterprises may take a long time to move, there are so many participants involved, it is difficult to fathom them all acting at once, at least, until some major content providers, major search engines, etc, announce they will _stop_ providing services over V4. <snip> -- -J
