ipv6

Any idea how to hide my ipv6 address. It leaks to some websites and I cannot access them because they can see where I am located.

There is no way to hide your IP address.
If there was and you would do so, your ISP would not know it is you and refuses your connection.

What I mean. When using vpn and router has not ipv6 turned off the websites on the other side recognize where I am and refuse to show the content because it can be seen only in the particular country.
It is any way that ipv6 is turned on and vpn doesn’t leaks the ipv6 address to the website?
