My local isp does not have IPv6 support. They are totally shit. I intend to change them. I triend https://test-ipv6.com/ site to check if my connection is ipv6 enable or not.

Here ISPs often offer ipv6 support on mobile networks but not broadband network.I guess because Mobile network is priced on a by-data basis while broadband is prices on  by-time basis.And yes,some areas have ipv6 support on both networks and previously people can access google ipv6 version,bypassing the GFW to some extent.
