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?

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.

Tor is used relatively little in Iran - https://metrics.torproject.org/userstats-bridge-country.html...

Other tools are much, much more popular, such as Psiphon, Lantern, MahsaNG, etc.

yes, my ex gf from iran also used Psiphon, I didn't trust psiphon that much but it seems that its decently well

In the end I had suggested her protonvpn as psiphon had some issues.

How does Psiphon work and how does it compare with protonvpn? I still trust protonvpn (which has free access as well) more than Psiphon fwiw.

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.
