It at least provides essentially native dual stack environment. The only difference is that your IPv6 access is via a tunnel. You'll probably be limited to a /56 or less over 6rd, unfortunately, but, because of the awful way 6rd consumes addresses, handing out /48s would be utterly impractical. Free.fr stuck their customers with /60s, which is hopefully a very temporary situation. > > I spoke with impulse.net last year, which appears to serve large > portions of the AT&T cable plant in Southern California.

If /56 or worse /60 or worst of all, /64 become widespread trends, it may significantly impact, delay, or even prevent innovations in the end-user networking/consumer electronics markets. Owen
