I have encountered multiple IPv6-only domains - certain random domains were accessible through Chrome, but unreachable from any command line tools. Turns out they were IPv6-only, and Chrome was doing its own DNS resolution, while anything that was using the platform DNS stack was hitting a black hole between OPNsense and my ONT.
