Comment on What is the deal with IPv6?
kent_eh@lemmy.ca 6 hours agoMobile carriers are mostly IPv6-only these days.
I was going to point that out as well.
Your phone is probably on an IP6 network right now.
And it will be NATted to an IP4 address when it leaves the carrier’s network to interact with the public internet.

Does that mean you can use IP6 to connect despite CGNAT, or do the ISPs that use it tend to firewall off the IP6 connections anyway?

If your ISP supports IPv6, then yes, you can use IPv6 to get a publicly reachable address when you would otherwise be unable to due to being behind a CGNAT. If your ISP does not support IPv6, you are out of luck. There are methods to translate between IPv4 and IPv6, but they require a public IPv4 address.
My friend switched to Starlink recently and was disappointed to find out he can’t host Minecraft servers and such due to CGNAT. Luckily, Starlink does support IPv6, so he was able to host his servers that way. The caveat is that we have to be IPv6 capable to join his server.
