RE: NY Times on IPv4 depletion

[<david.binet () orange-ftgroup com>]

Dear all,

Actually I fully agree with Cameron. 
> From an operator point of view, it is quite difficult to rely on some specific functions in mobile, besides an IPv6 
> stack - that is already difficult to get if we have a look on IPv6-ready devices available on market. I do not know 
> how we can mandate some DS-lite functions in devices, for example, as far as there is no document where 3GPP devices 
> are "specified". So, it is not possible to set up some IPv6 introduction strategy based on some solutions integrated 
> in devices. In mobile context, I think it is more adapted to encourage IPv6 native communications and to rely on NAT64 
> for IPv4-only appls access even if we all know that such translation solution has some drawbacks.
