Disable IPV6

[nishsheth]

Please disable ipv6 on my router. I need this to use dns proxy for my work which does not work if ipv6 is enabled.

IPv6 will not be disabled once you have it. Off course you can always disable IPv6 on your local machine as a workaround. That would be the quickest solution for now.

If you are a more advanced user and have your own equipment it is also possible to create a separate IPv4 only VLAN which then can be used for all devices in need for this IPv4 only proxy.
