title: Disable iCloud Private Relay
discussion: |
  Enterprise networks may be required to audit all network traffic by policy, therefore, iCloud Private Relay _MUST_ be disabled.

  Network administrators can also prevent the use of this feature by blocking DNS resolution of mask.icloud.com and mask-h2.icloud.com.
