Why does my IPv6 say no Internet access?

There could be various reasons for this network error; some of the common ones are mentioned here:

  • Misconfigured network settings – The network settings, if not configured properly, could cause this network error. Try renewing or releasing the IP configuration or disabling IPv6.

  • Firewall interference – Something firewall settings set could restrict the network access causing all types of problems. Try disabling the antivirus and turning off the firewall temporarily.

Now that you know the causes of the issue, let us move on to the troubleshooting solutions.

Do I need IPv6 Internet access?

IPv6, the sixth version of Internet Protocol, was introduced in 1998 and was eventually supposed to replace IPv4.

It is longer than an IPv4 address, meaning it allows you to create more unique addresses, and IPv6 uses a 128-bit address & capable of providing 340 undecillion IP addresses.

Most websites and search engines still support IPv4, but some support IPv6 as well; therefore disabling the latter would not be a great option.

Additionally, disabling it could cause issues if your router is using an IPv6 address. That’s why there is no harm in keeping both of them enabled.

  • Turn off real-time protection on your third-party antivirus (if applicable).
