IPv6 over IPv4 Tunnel to Bypass Router-Level YouTube Slowdown

IPv6 tunnels over IPv4 help you access sites and services that use the IPv6 protocol, even if you have an IP version 4 (IPv4) address. To set it up, you need to register on the website of a provider that provides such a service (also called a tunnel broker) and uses 6in4 technology. After registration, you will receive all the necessary data for connection.

One of the advantages of this method is that you don’t need to configure anything additionally on other devices in the local network, the work on Android TV won’t break, etc.

The tunnel only works with a white IP address (some providers give it out for free, some for a certain amount per month).

You can check whether your IP address is white or not by comparing the addresses that the provider issues to the router (look in the router's web interface) and on the website https://myip.ru (but even if they match, it is better to check with the provider's technical support once again, for example, Beeline could previously issue either white or gray IP addresses). This method is not a 100% panacea, the slowdown can also work on IPv6.

The functionality was tested on three different providers in Yekaterinburg – it worked everywhere, but the solution is not 100%, there are reports that this method does not help on Rostelecom.
