We have gigabit fibre with 2degrees at present. We're looking around at different provider options, we could probably save $20/m with our existing provider but it's a good time to shop around and see what's what.


Is the CGNAT thing actually worth worrying about, if the provider has IPV6? If the provider doesn't have IPV6 I take it CGNAT is a must these days?


Our typical use is a family of 4, mixture of gaming (sometimes 4 people at a time), youtube, sometimes downloads, very occasional streaming.

If you don't run any services from your connection (game servers etc), then CGNAT is not a concern for general internet usage as you've described. IPV6 is not a concern either, as there are no mainstream services out there that demand IPV6.

The place you are connecting from needs to have ipV6 for the v6 address to be any use. And the NZ mobile networks are well behind the curve on that.

On your mobile, if your mobile provider does not support IPv6, it is possible to set up an OpenVPN connection (or possibly other VPN types) and bring that up on your mobile to connect to your home network.  Then the mobile can use IPv6 via the VPN.  I have had this working for many years now.  But you can not run your own OpenVPN server over a CG-NAT connection, and I am not sure if the other options that do work with CG-NAT (such as Tailscale) would allow you to do IPv6 over them.
