Parent commenter wasn't saying that CG NAT costs could be avoided entirely. Deploying IPv6 gets Netflix, YouTube, Facebook and other popular traffic to connect directly. That means less racks of CG NAT.
- 2fastpost 5y agoLike I said, you can only avoid CGNAT costs if you accept the failure modes inherent if/when your IPv6 fails. Thus in a properly designed network these are not optional costs.
- Dagger2 5y agoYou do avoid some of the cost, because you can direct a significant amount of your traffic over v6 and not need to CGNAT it. The failure mode for your v6 failing is the same as it is for v4 failing in a v4-only ISP: stuff breaks. If you want to fix that you need a redundant failover setup, which is the same thing you need in v4 except cheaper because it doesn't need to do CGNAT.
