On iOS devices, you may see strange privacy warnings indicating that your network is blocking encrypted DNS traffic. News like this can be very worrisome. But what exactly does that mean? This means that other devices connected to the same network can see and record the websites you visit on your iOS device. However, as long as you use the SSL protocol, no one knows what you are doing with these websites.

 Suppose someone wants to access and analyze router data in order to spy on you. If your network is blocking encrypted DNS traffic, you can see that you've accessed Facebook, but you can't see the encrypted traffic itself. I can't access the data exchanged between iPhone and Facebook.

There are two main reasons why network administrators block WiFi-encrypted DNS traffic. One of them is notorious for these websites being insecure for computer security. You can prevent this by configuring your wireless router to use Secure Socket Layer and port forwarding. Another reason is that some websites can use private address masking to gain unauthorized access to your account. Fortunately, these methods are not difficult.

 The first reason encrypted DNS traffic is blocked on a WIFI network is that the network can monitor the names of websites and servers. This means that the names of these websites and servers are recorded by other devices on the network. You can prevent this by setting parental controls on your device. The second reason your network may not support encrypted DNS is that it is insecure. In most cases, this issue cannot be fixed.

 The second reason your network blocks encrypted DNS traffic is to block DNS encryption. If you are using public WiFi, other devices on your network may also be listening to encrypted DNS traffic. This is because you can monitor the names of websites and servers on your network. It is important to check your network's DNS server to make sure that encryption is supported.

 Another reason your network blocks encrypted DNS traffic is to block DNS requests. This is because the network may be blocking connections by monitoring websites and server names. In fact, you can also track and record the domains that your device visits, so you need to make sure you're not visiting malicious websites. If you don't have a good security solution, it's not worth worrying about.

Well, it means that other devices connected to the same network can see what sites you're visiting on your iOS device and record that information. However, nobody can see what you're doing on those websites as long as they use the SSL protocol. 

If the network is blocking encrypted DNS traffic, they can see you visited Facebook but can't see the encrypted traffic itself. They don't have access to the data exchanged between your iPhone and Facebook.

What does a VPN actually hide and do? By force, I will be jaded. A vpn hides your IP address (as long as your vpn is not at your home) by creating a virtual tunnel. See a bit like a channel (where everyone draws water) (normal connection) and your garden hoses (vpn) where you and the vpn know where the source is and where the destination is. A vpn will encrypt your traffic so that your ISP only sees secure traffic to which it does not have access. It can also give you access to a corporate network (if it's corporate vpn) or your home if configured for it. Allowed, filtered, blocked certain service/port. A vpn is the postman, you forward your mail to it, and it delivers it to you. Except that the postman (vpn) here has access to almost all the content. So you make a transfer. Instead of it being the ISP of your country or city, it will be the vpn of country x that will hold the info about you. Site visited, and all unencrypted traffic.
