# Custom Domain Blocking

{% hint style="info" %}
This feature is available in the **Premium plan and higher**.
{% endhint %}

You may set up Custom Domain Blocking in [Control Panel > Settings > Threat Blocker & DNS](https://app.goodaccess.com/threat-blocker-and-dns/).

The Custom Domain Blocking feature allows you to restrict access to specific domains, ensuring a secure environment where users cannot navigate to prohibited websites.

To block a specific domain, click the **+ Add domains** button.

You may specify the domain by its domain name or IP address.

Don't forget to **Enable Custom Domain Blocking**, and **Save changes**.
