alt Hacker Newsmarcosdumay's comment of here explained situation (giving it more attention)
they can censor IPv4 when they want, but they don't know how to censor IPv6. So they block it entirely.
This is the reason why they aren't blacking out IPv4
From my own experience, my ex gf was iranian. She was using discord via some psiphon vpn or something iirc idk how she got access to it but she had it.
I didn't trust psiphon that much so I asked her to install proton vpn and it did work. I wanted to play minecraft with her so prismlauncher but resources couldn't be downloaded so I made her download protonvpn so that she can play minecraft with me/install it (piracy was forced and also at that point necessary)
She was using tlauncher which somehow worked but tlauncher was russian spyware and prism launcher was open source
I talked to her about how she could use stablecoins crypto but crypto was illegal so ended up not suggesting it in the end to prevent inflation or talked to her about gold which is wild considering its like 3-4 months after we broke up but inflation is at 50% now.
Anyways the point being that protonvpn worked and other vpn worked too.
My question is, would things like protonvpn work after this blackout? I mean marco's and other comments in a thread explain to me that ipv4 can be blocked by them so I presume vpn's for ipv4 would shut down. And so vpns would most likely be using ipv6 which got blocked down
So does that mean that now Iranian people can't access vpns?
I also saw the other day some video about how when people called Iranian numbers from outside countries some random AI robot ass voice called and asked who are you and who are you talking to? And gave pause, and the most logical explaination to it was that the govt was recording these things so dont say anything to them. It was a creepypasta video.
Briar might help but Briar still leaks some metadata when I talked to their authors or heard about it online.
Instagram isn't blocked in Iran so are these social media apps still there after the blackout?
This raises so many questions and wtf is happening in the world

Most of what's happening in the word can be boiled down to either someone craving power, or someone in power desperately struggling to hold on to it.
It depends on how they do it, but you can shut down the router ports that connect to the rest of the world easily if they want.
Internet participation is voluntary between countries.
> they can censor IPv4 when they want, but they don't know how to censor IPv6
I'm curious why this is the case? As far as I know the primary benefits of v6 is just the increased address space. Does it provide any privacy benefits? What would prevent Iran from doing the same censorship?
