Pretty much anything is lower than the cost of IPv6 deployment if you already have a large IPv4 deployment.

- lmm 3y agoCGNAT routers aren't cheap. At some point you're spending more keeping your IPv4 running than it would take to replace it.
- j16sdiz 3y agoExcept you can't really replace it. You need to keep BOTH for the good old internet to work.
- lmm 3y agoYou probably need some amount of CGNAT or equivalent (e.g. DS-Lite). But if you offload the vast majority of your traffic onto v6 (which is easier than it sounds, because most traffic is to a few big sites and most of them are v6-enabled) then you can reduce the number of connections you have to track by orders of magnitude, which saves you real money.
- ThatPlayer 3y agoYeah I remember seeing that in a talk about an ISP adding IPv6 support: https://youtu.be/75h4gm7t1oI https://youtu.be/75h4gm7t1oI . They say that 30% of traffic is IPv6, which means 30% less CGNAT hardware needed.
