# xp.apple.com

`xp.apple.com` is an Apple host. Apple lists it in the Software updates section of its host list for every platform, but gives no description.

Run by Apple · Ports: 443 TCP · Checked: 1 November 2026

## Short answer

An Apple host that Apple lists in the software update section of its host list, without saying what it does.

Block with care

Apple doesn't say what it does, only that devices need it for software updates. Blocking it may affect updates.

Matches

`xp.apple.com`

A name with `*.` covers every name under it: `*.push.apple.com` matches `1-courier.push.apple.com`.

## What it serves

Apple's enterprise host list names `xp.apple.com` in its Software updates section, on port 443, for iOS, iPadOS, tvOS, macOS and visionOS. It supports proxies.

The description column for it is empty. Apple doesn't document what it serves.

A similar name, `xp-cdn.apple.com`, is listed for Content Caching “Reporting”. That is a different host, and Apple doesn't say they are related.

## Processes that use it

- [softwareupdated](https://kilobat.app/processes/softwareupdated): Part of macOS. It checks for and downloads macOS updates, security responses and system files.

## What breaks if you block it

Block with care

Apple doesn't say what it does, only that devices need it for software updates. Blocking it may affect updates.

What breaks if you block it

- Not documented. Because Apple lists it for software updates, updates may fail or report incomplete status.

With Kilobat Pro and the network filter, you can block a host for every app or for one app: in Connections, select a connection and choose Block. Apple’s own services are never blocked by Kilobat’s [Protection](https://kilobat.app/docs/blocking#protection) lists.

## Notes

Kilobat doesn't guess what an undocumented host does. This page describes only what Apple's list says.

Apple says that its services fail connections that use HTTPS interception.

## Apple’s rules for its hosts

Apple’s list, [Use Apple products on enterprise networks](https://support.apple.com/en-us/101555), says that devices open these connections, not Apple’s servers. Apple services fail any connection that uses HTTPS interception, so a proxy that inspects TLS should leave Apple’s hosts alone.

If a firewall allows hosts by name, allowing `*.apple.com` covers most Apple services, Apple says. A firewall that works only with addresses can allow `17.0.0.0/8` for IPv4, and `2403:300::/32`, `2620:149::/32` and `2a01:b740::/32` for IPv6.

To see which app on your Mac opened a connection to this host, use Kilobat’s Connections tab, or the [agent network log](https://kilobat.app/docs/agents#agent-network-log) for AI agents.
