How to tunnel an Ipv6 to an Ipv4?

I was looking for an ipv6 provider, as they are cheaper than ipv4, but my instagram bot doesn't allow ipv6 connections. I heard that you can tunnel ipv6 to ipv4, or something similar. I tried to learn from internet, I read a lot, but I couldn't find anything interesting.

Any of you know how to do that?

Thanks in advance!!

i think you need access to the machine itself to do that...
