The key problem with DS-Lite that I see is that it requires CPE config - it's just too much hassle. Seems to be easier to go for CGN (with all the problems that entails).

As an ISP'll end up with collisions with their customers if RFC1918 space is used for their intermediary/ISP portion of NAT444, a new /10 (specifically 100.64.0.0/10) was allocated for this use. RFC6598 details the allocation, and the use cases for it.

Is there anyone here who has had to choose between CGN and dual-stack lite and is willing to say why they made the choice they did. I’m familiar with the various possible issues and I’m interested in hearing about what people’s actual issues have been.

Cheers,
