iCloud Private Relay

What is iCloud Private Relay:

iCloud Private Relay is a privacy preserving feature that is built in to iOS and macOS when you have an iCloud subscription. This only works in Safari and other supported Apple applications. Normally, when you try to go to a website (e.g. google.com), your computer will reach out to a DNS (Domain Name System) server that tells your computer the IP address of the website (e.g. 142.250.72.14). This request is done in plain text (unencrypted) between your computer to the server, meaning that the server (or anyone listening) will know exactly who you are and what website you are trying to go to. iCloud Private Relay uses encryption and multiple different servers so that it is not possible to know both who you are and what website you are trying to go to.

Why you are receiving this notification:

At IAS, we have our own DNS servers that have their own security settings enabled that help us keep the network secure. For example, we maintain a list of domains that we block because they host malware or phishing websites. For any device that is connected to our networks, both wired and wireless, we require that device to use our DNS servers. Since iCloud Private Relay bypasses our DNS, it has been blocked on the IAS networks. This has been in place for a while now. Previously, any of your devices that ran into this issue would have automatically dropped the iCloud Private Relay and used our DNS without you even knowing, but Apple wanted to make people aware that iCloud Private Relay was not actually being used.
