I will check but as far as I know my ISP (Verizon FIOS) does not support IPv6 to me. So it's not an option for me but I'll check.NetGuard supports IPv6, but it is up to apps to use this. In any case NetGuard cannot force apps to use a specific IP version.
But, I assume that NetGuard hides my IP address. Am I correct?
I have location permanently off on my phone. Anything else I should do to improve phone security?
