[Feature] Support IPv6

Is your feature request related to a problem? Please describe.
ipv6 seems to not be supported or not be supported well, on the android app the only thing it says is 'v4-wlan0' and on the cli there seems to be no option to force a specific version and wireshark seems to show it's using v4

Describe the solution you'd like
support ipv6 and have an option to force 1 or the other
