# *.dropboxusercontent.com

Hosts under `dropboxusercontent.com`, such as `dl.dropboxusercontent.com` and `dl-eu.dropboxusercontent.com`, are on Dropbox's list of verified domains.

Run by Dropbox · Checked: 1 November 2026

## Short answer

A Dropbox domain on its list of verified domains, with hosts such as dl.dropboxusercontent.com.

Block with care

Blocking them can break Dropbox downloads, shared links and syncing. Dropbox doesn't document each host's role.

Matches

`*.dropboxusercontent.com`

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

## What it serves

Dropbox's help lists `dl.dropboxusercontent.com`, `dl-eu.dropboxusercontent.com` and `*.dl-eu.dropboxusercontent.com` among the verified domains that you usually don't see in your browser's address bar.

The names point to downloads, but Dropbox doesn't describe what each host serves.

Dropbox doesn't say which features use each host. It recommends allowing its domain names in a firewall.

## Processes that use it

- [Dropbox](https://kilobat.app/processes/dropbox): The Dropbox desktop app. It uploads and downloads your Dropbox files, and with LAN sync it finds other Dropbox computers on the local network.

## What breaks if you block it

Block with care

Blocking them can break Dropbox downloads, shared links and syncing. Dropbox doesn't document each host's role.

What breaks if you block it

- Downloads from Dropbox, including shared links, may fail.
- Syncing in the desktop app may fail.

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.
