Do not have access to IPv6: is this the fault of Linux, the router/modem, or the ISP?
by grumpyskeptic from LinuxQuestions.org on (#5N38M)
I am using Linux Mint 20.2 Mate.
According to https://test-ipv6.com/ and another similar website I do not have any access to IPv6.
How can I find out where the fault is?
Does Linux Mint forbid IPv6? In the past IPv6 was thought of as a security risk, I do not know if it still is. Where in the settings can I see if IPv6 is potentially active or not?
I have tinkered with my router/modem in the past so I may have turned it off perhaps, but I cannot find any mention of either IPv6 or IPv4 in its config file. Does it have some other name?
The website above says: "Your DNS server (possibly run by your ISP) appears to have no access to the IPv6 Internet, or is not configured to use it. This may in the future restrict your ability to reach IPv6-only sites."
Could the ISP (Talktalk UK) restrict access to IPv6 or is this very unlikely?
My router-modem is set up to use an external DNS Server for IPv4 rather than that of the ISP, but not for IPv6.
Thanks.
