In his webcast, Cisco subject matter expert Phil Remaker provides a simple overview of a dual IPv6 and IPv6 stacked environment and explains typical failure modes in IPv6 transport and DNS that might be experienced. He introduces some websites you can use to test your IPv6 connectivity in advance of World IPv6 Day and talks about IPv6 connectivity options for websites and end users.

Phil Remaker is a distinguished support engineer at Cisco and is recognized for his wide range of knowledge and skills in Cisco products, networking protocols, and systems. He currently works as a technical leader in the Cisco Services Technical Services organization focusing on vexing problems around security, software release, and product manageability.
