It's never ipv6 only. There is an ipv4 address too. Not sure how that works, but ipv6-test.com shows both versions of addresses.

- Volundr 6y agoKind of. In practice your right, basically every ipv6-only ISP will run NAT64/DNS64 so you can access the ipv4 only web, but there's no technical reason they HAVE to, just a commercial one. And you have far less control of that ipv4 address than you would even a dynamic ipv4 assigned to your router.
- Dagger2 6y agoThat said, NAT64/DNS64 is v6-only from the perspective of clients on that ISP. The v4 internet will be mapped into a v6 /96, but from the client perspective it's just the same as any other v6 prefix.
