# *.mzstatic.com

Hosts under `mzstatic.com` belong to Apple. Apple lists the domain for store content, such as apps, books and music, and apps from websites and alternative marketplaces.

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

## Short answer

An Apple domain for store content such as apps, books and music, and apps from websites and alternative marketplaces.

Block with care

Blocking it breaks some App Store content. Apps you already have keep working.

Matches

`*.mzstatic.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 `*.mzstatic.com` in its Apps and additional content section, on port 443.

Apple's description also names apps from websites and alternative marketplaces.

On a Mac, App Store content and downloads belong to [`appstoreagent`](https://kilobat.app/processes/appstoreagent) and the App Store app.

## 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 breaks some App Store content. Apps you already have keep working.

What breaks if you block it

- Store content hosted there, such as apps, books and music, 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.
