IPv4 is sanctioned/heavily restricted in iran as well, I mean very high filtering

The reason they didn't do this for ipv6 is because ipv6 obviously has a lot more addresses and so they just ended up blocking it whole.

Atleast that's what I read in one of the comment threads discussions in here

I don't think that in iran there would still be any available ipv4 entry nodes that they would allow. They would filter/block it as well?
