- Network connections to the hosts below are initiated by the device, not by hosts operated by Apple.
- Apple services will fail any connection that uses HTTPS Interception (SSL Inspection). If the HTTPS traffic traverses a web proxy, disable HTTPS Interception for the hosts listed in this article.
Make sure your Apple devices can access the hosts listed below.
