alt Hacker NewsIPv4 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?

Right, I should have written "IPv4 bridges" (which can be obfuscated and distributed out of band), not "IPv4 entry nodes": https://bridges.torproject.org/
But you can reach the IPv6 internet through those too.

That's what bridges are for.
Blocking is a cat and mouse game. It depends how heavy handed they are about it, but unless they totally cut off the external internet, its unlikely tor is 100% blocked, although it might be effectively blocked for most people.
