I use VPN most of the time. My work requires it, and I like Mozilla VPN for personal privacy. (Note: it has ad blocking DNS built in which is nice!)
I occasionally get blocked by websites or services, especially streaming apps, if I'm on VPN. I suspect they're just looking out for Amazon/Microsoft/etc IP address blocks. It's very annoying
Mozilla VPN runs on Mullvad who are transparent and publish active server and IP lists https://mullvad.net/en/servers.so trivial to block them without blocking all of Azure/GCP/AWS[1]
There are also third party providers of IP annotations to classify known VPN address ranges that content providers typically subscribe to blanket block providers.
The reason for this aggressive approach is streaming apps all need your IP as core signal for tagging your region and all content licensing is region locked (even on YT).
Netflix are/were the most relaxed about it , and for long time would only buy content if they got global distribution rights, but not anymore. Many VPN ads specifically used to market that you can watch Netflix geolocked content.
[1] IME they block DC IPs too although not needed for blocking professional VPN, even self hosted OpenVPN on cloud box usually gets flagged.
That's not the same. You get blocked because the IP address you're coming from is associated with a VPN list, not because they're analyzing the traffic in detail.
The simplest methods block known datacenter IP ranges like you thought. More will score it based on several heuristics and a reputation over time. If you get 100 different users connecting from a single IP, it's probably not someone's home internet connection.
Depends on how you define "reliably". You can get pretty damn close by triangulating on traffic patterns and browser fingerprinting. There is a lot of research in this area. But it'll never be perfect.
This requires a lot of extra work though, and extra work is downward pressure on the behavior (underage people looking at pornography) that the state of Utah is trying to exert downward pressure on.
The inability to immediately and perfectly eliminate a behavior is not a good enough reason to be against any attempt to eliminate that behavior.

So if you are legally required to block all VPN users and then fail to actually block all VPN users what is stopping you from being punished for not complying with the law?
Yes but isn't it suspicious that all your traffic goes to the friend's house and not to Facebook and Reddit? If you claim it is not a VPN does it mean your friend is providing illegal unlicensed hosting? That's even worse.
Split tunnel is a thing, and in that instance the platform required to comply (like a porn site) doesn’t have any way to see all your traffic to determine if it’s a VPN/proxy connection or not.
You do not need to know "reliably". You can block everything remotely suspicious, and in case someone is blocked by mistake, they can file an application with all necessary documentation proving the connection is not a VPN.
There are a category of things that are technically impossible until a burly man threatens to break your arm if you don't do them, and a category of things that are still impossible.
Doesn't help your arm, but when they're asking for things in that second category, it doesn't help them either.
>As we’ve said time and time again: the internet will always route around censorship.
Is this still true, or has it become a truism? It seems nations like Iran and China (and events like Kashmir come to mind) have progressed the state-of-the-art and playbook to where we can't actually say it definitively will route around it.
Now seeing that the US and EU are flirting with these similar restrictions it's making me wonder how we'll be able to keep hold of these principles.
Maybe my concern with that adage is ultimately its passive voice, since it takes 'active' action by people to give us those options, and will probably take more actions by more people to keep it alive now.
The thing China can do, and does do: Kill your network connections, whether that's a TCP session, your ability to send or receive packets with some particular IP addresses, or at the extreme armed men show up and now it's not an Internet problem.
Things China can't do: Magically "downgrade", "decrypt" or "intercept" the secure protocols we use every day like HTTPS. Facts won't budge, the technology we are using does what it says on the tin.
The Internet can't route around you being thrown off a tall building by men with guns, but the IETF has for some years considered it to be extremely important to design the network protocols to prevent these shenanigans. BCP # 188 "Pervasive Monitoring is An Attack"
Is China that successful at it lately? I see a lot of posters and info from China getting around the great firewall, and my understanding was that they don't really care if 1% of users do that so long as it mostly holds and only the technical minded or really fixated will see it.
So there is a route around censorship, but maybe the public doesn't really care about it.
There is also the difficult reality that the government doesn't need to block vpn entirely, but just make it a credible risk of being detected. If you have to worry about the state police barging into your home, you are likely to decide it isn't worth the risk and self-regulate.
I'm not sure whether it's 1% or 0.1% or only Xi Jinpin can access YouTube. China can adjust the surveillance level dynamically. It's a matter of cost and effect.
The layer 2 and 3 of ISO/OSI stack does indeed "route around censorship". But the Internet as we know it is all Layer 7, and it's as centralized as it gets.
That's why regulators often aim straight at Layer 7 entities - companies providing consumer services over the web. Because no matter how unblockable the route between you and some server is, it doesn't mean anything when the server itself is refusing to talk to you.
What about p2p and less scrupulous actors like TPB? I guess in China the former is probably more effective but this sort of thing is immediately what I thought of when I read OP
I’m pretty sure with Iran, and I assume other authoritarian nations, the state controls what traffic can and cannot leave their borders. When they go dark, they just effectively cut off access to the outside world entirely. Sure they may have their own state run servers that provide some services, but then they can inspect and manage all traffic being routed inside the country. Don’t have to try and find the VPN if there’s just no traffic.
I suppose Utah could impose some sort of strategy here, but would be so burdensome and anti-American I’m not sure they could pull it off. Instead of a blacklist of sites dictated by the site provider, you go the other way where all Utah ISPs maintain a whitelist of IPs permitted to Utah citizens. Any traffic attempting to reach a non-white listed IP, would be rejected.
Not sure what the impossibility is. VPN's have a set of exit relays. If traffic is coming from one of those exit relays, it's coming from a VPN, so adult websites can be required to block traffic from those exit relays. What am I missing?
The law is only meant to apply to citizens of Utah though. Blocking all exit relays would mean that absolutely anyone accessing that website would not be able to do so from a VPN which burdens people outside of Utah too.
The law likely violates the U.S. Constitution’s prohibition on passing laws that significantly burden businesses and people outside Utah’s borders.
SB 73 burdens the rights of all internet users outside of Utah because it requires adult websites to either know every visiting user’s physical location, and then block those in Utah, or to verify every visitor’s age just in case they might be in Utah.
It's technically impossible to both implement Utah's law and respect the constitution. To make it technically feasible you'd need to either change the constitution or federalize the law.
I would think that requiring adult websites to essentially block all VPN traffic to be pretty heavy handed and hardly a solution. Especially considering there are many reasons to use a VPN.
It's impossible to have a full and complete list of VPN exit nodes, for the simple reason that no company publishes the full list, and also technically if you set up an OpenVPN server on digital ocean and connect to that you're also using a VPN but no one would know your address is hosting a VPN server.
You'd have to ask every non-residential host online to do the same. As above, you can get a DigitalOcean droplet and ssh -D to it, now you have a SOCKS proxy that for state's concern is doing the same as a VPN.
Utah could demand the moon, it doesn't mean that the federal government would agree they have a right to that demand.
Utah can't tell businesses that service the country (or the world) how to do anything in this regard. You can't demand a list of the VPN exit nodes, because no VPN would ever give you that, and if they're outside of your jurisdiction, how could you possibly enforce it (assuming you got the Feds to agree with your law regulating interstate/international commerce now). You can't tell websites to only accept residential traffic, for the same reasons.
The internet sorta fucks states rights (in a good way).
Why would a VPN company care about what Utah requires if they have no legal presence there(or in the US for that matter)?
Besides, there's no such thing as "residential" IPs. If I set a VPN gate at my mum's house, how would the porn company know?
The "impossibility" is in them saying "we cannot guarantee with 100% certainty that the user isn't using a VPN" and that's correct, they can't - but the law has no provision for that, they are risking fines over something they cannot control.
Is it even possible to reliably know that a connection is from a VPN? Anyone can proxy through a random hosting provider.

Since when do you have to pull permits to put a server on the web?
Let’s block traffic on the internet blindly just in case someone is looking at an adult website.

A VPN/proxy could exist at almost any single address at any given time.
This Utah law requires perfection.
How is that not a blatant first amendment violation?
It's impossible to have perfect knowledge of the entire set of VPN exit node addresses.
It also seems to me like Utah could just demand that adult sites only accept traffic from residential ips.
