- 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.
