How and is it possible to set up a proxy server based on 6to4?

Question

Debian

Greetings.
At the moment, I have to parse a lot of information from social networks, they support ipv6, so I solved the problem for myself with a proxy by renting vps and buying 250 ipv6 addresses; configured 3proxy so that when accessing the server ip, external ipv6 is determined by port.
Now I read about the 6to4 technology, which allows you to make tunnels and wondered: is it possible in this case to do without purchased ipv6 addresses, and based on your static external ip, create a lot of version 6 addresses to access remote resources.
Those. in fact, arrange a proxy server for yourself, but without buying external ipv6 addresses, but based on generating from ipv4?
I will gladly transfer 10-15 bucks to someone who will explain the essence and show how to set it up for debian

Answer 2

Establish a tunnel to the ipv6 Internet based on the existing ipv4 address. One , two .
