So am I to understand that services like Toredo client (which is what I PRESUME is being discussed) is on automatically in some Windows desktop systems? The drafts I saw posted earlier were discussing what is essentially toredo services (anycast tunnel) at least. If this is on by default, then that is only bad (in my opinion) IF there is no native IPv6 support on the LAN side of these networks. Maybe I am missing something, but this is my take.
More ipv6 leadership from the Comcast camp. Keep it up.
Seems to me that if Comcast has "announced IPv6 support" and it is not NATIVE IPV6 support, then that is certainly a problem. Either way, there certainly IS a place in networks for Toredo services, since SO MANY devices for the CPE end of the connectivity equation still have zero support for IPv6. It's not the best solution for sure, but the fact remains that most networks will be dual-stacked at least initially at the core, but the endpoints (customer networks) are outside of our administrative control and often are behind devices that we do not control/own. Maybe I'm missing something... -- ******************************************************************** * Butch Evans * Professional Network Consultation* * http://www.butchevans.com/ * Network Engineering * * http://store.wispgear.net/ * Wired or Wireless Networks * * http://blog.butchevans.com/ * ImageStream, Mikrotik and MORE! * * NOTE MY NEW NUMBER: 702-537-0979 * ********************************************************************
