# Top-level Domains Blocking

If you want to block any top-level domain, just add it without a leading dot to your **Denylist**.

For example, if you want to block access to all websites in the RU domain zone, add **ru** to your Denylist.

Internationalized country code top-level domains should be added to the Denylist list in the IDN form:   
**中国** (Chinese IDN ccTLD), **рф** (Russian IDN ccTLD), etc.

<p class="callout info">A full list of top-level domains can be found on the [IANA website](https://www.iana.org/domains/root/db) and [Wikipedia](https://en.wikipedia.org/wiki/Country_code_top-level_domain).</p>
