The only thing operators have to know about IPv6 is that IPv6, as is currently specified, is not operational.
I think it is safe to say that this is provably false. Are there opportunities for increased efficiency, perhaps ... however: I get native IPv6 at home via my standard residential cable connection using off the shelf CPE gear and standard OSes. I get native IPv6 via my standard LTE devices, again - off the shelf - no customization required. *(Repeated emphasis on the use of standard, off the shelf components here ... no end-user hacking/tweaking, nor custom firmware loads, nor special requests to the provider ... "it just works".)* * * Both of these have been properly functioning since being lit up. Clearly, atleast the two *rather large* operators involved *(Comcast & Verizon Wireless, if it matters) *have deployed IPv6 in an operational fashion. I bet Hurricane Electric would *strongly* disagree as well. *... Not to mention the enterprise networks and hosting facilities that have also implemented IPv6 rather successfully, all of which are relying on some carrier(s) to provide them connectivity.* /TJ
