Updates and downloads

# *.itunes.apple.com

Hosts under `itunes.apple.com` serve “store content such as apps, books, and music”, Apple says. App Store downloads and updates use them.

Run by Apple · Ports: 443 and 80 TCP · Checked: 1 November 2026

## Short answer

Apple's store content host, for apps, books and music.

Block with care

Blocking it stops App Store downloads and updates, and other store content. Turn off automatic updates instead.

Matches

`*.itunes.apple.com` `itunes.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 `*.itunes.apple.com` and `itunes.apple.com` in its Apps and additional content section, on ports 443 and 80, with proxy support.

On a Mac, App Store downloads and updates run in [`appstoreagent`](https://kilobat.app/processes/appstoreagent) and `appstored`.

Apple also lists `vpp.itunes.apple.com` for device management of Apps and Books licences.

## Processes that use it

- [appstoreagent](https://kilobat.app/processes/appstoreagent): Part of macOS. They download and update apps from the App Store, so app downloads show under them, not under the App Store app.

## What breaks if you block it

Block with care

Blocking it stops App Store downloads and updates, and other store content. Turn off automatic updates instead.

What breaks if you block it

- App Store apps can't install or update.
- Books, music and other store content may not download.

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.

## 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.
