No competent network engineer wants to work in Iran, so government doesn't know how to block v6 properly. End result: just get rid of it entirely!

Why would they want to block IPv6 specifically?

Because v6 IPs are cheap, expendable and routing it over encrypted tunnels does not look suspicious. Anyone can buy a block and with little help announce them from multiple locations including home, mobile, uni wifi, and route further from there.

If you want a sober and thorough analysis then using a single source is a bad idea. This does not involve feelings, in fact, quite the opposite.

If you want my feelings, then yes, I do think it's chilling that people can satisfy themselves that a few select videos from a foreign area is enough intelligence to make a decision about war.

If you've never had the pleasure of working in a war zone after the troops have left then I think you should ponder the consequences of your analysis a little more deeply.

Especially ones in a station wagon full of tapes hurtling down the highway. But seriously?

There are mesh networks, but even so IPv4 isn't down, and people can share files p2p.

Theoretically this is true, but in practice it's not. Most p2p services rely on the global internet in some way. The BitTorrent DHT, for example, is unlikely so self-heal in the event of a completely inaccessible global internet.

Things like HolePunch have a lot of potential here, but you'd need an Iran-only DHT, and it's just not deployed at scale.

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…

> 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, but it is more difficult than jamming a typical radio antenna because the starlink uses a directed beam rather than a omnidirectional radio broadcast. This either requires enormous amounts of power, targeting the satellite itself with a directed radio beam, or getting between the satellite and the ground station by bouncing a signal off the ionosphere. The above is for jamming directed beams in general. It is li…

Huge idiot here with an honest question: with starlink, could a rogue actor just point a bunch of high-powered lasers at the satellites and brick them?

Cheaper to launch a barrel of metal trash to the Starlink orbits. Or a few barrels. Iran has rockets for that.

that would make it much more suspicious the protests are being orchestrated from outside by CIA/Mossad... The "regime" is a republic with regularly held presidential (8 presidents in 45 years) and parliamentary elections. What would you like to replace it with? Monarchy

I would like people not to get killed when they protest I would like the internet not to get shut down during the protest Am I asking too much?
