# Rule for blocking black addresses

{% note info %}

The IP lists feature is at the [Preview](../../overview/concepts/launch-stages.md) stage.

{% endnote %}

Smart Web Security has [pre-installed lists](../concepts/lists.md#yc-rules) of untrusted (black) IP addresses. These lists streamline traffic checking and block requests from unsafe or suspicious addresses. Also, you can add [custom blacklists](../concepts/lists.md#user-rules).

## Set up a rule for blocking black addresses {#black-list-rule}

{% list tabs group=instructions %}

- Management console {#console}

  1. In the left-hand panel, click ![image](../../_assets/console-icons/shield.svg) **Security profiles** and select the profile.
  1. Click ![image](../../_assets/console-icons/plus.svg) **Add rule**.
  1. Enter a name for the rule, e.g., `block-by-list`.
  1. Set a higher **Priority** than that of the Smart Protection rules, e.g., `9100`.
  1. Enable **Only logging**.
  1. Specify the rule settings:

     * **Type**: `Base`.
     * **Action**: `Deny` or `Show CAPTCHA`.
     * **Traffic**: `On condition`.
     * **Conditions**: `IP`.
     * **Conditions for IP**: `IP belongs to the list`.
     * **IP belongs to the list**: Add [pre-installed lists](../concepts/lists.md#yc-rules) for filtering or your own blacklists. Requests from these addresses will be blocked.

     {% note tip %}

     We recommend that you immediately add these pre-installed blacklists: `is_ddoser`, `is_tor`, and `is_anonimous`.

     {% endnote %}
  1. Click **Add**.
