# IP filtering

Adding an IP to the lists **is your responsibility**.

{% hint style="info" %}
The devices synchronize the lists every half hour. It is therefore normal that the addition of an IP is not immediately reflected in the display of the flows.
{% endhint %}

**Blacklist**

The remote IP addresses and those associated with the domain names in this list will be monitored and filtered by the device.

#### Whitelist

The remote IP addresses in this list will not be filtered by the device.

{% hint style="danger" %}
By adding an IP from the CerbèreIPDB database to this list, you expose your network to possible attacks.
{% endhint %}

#### Suspicious remote IP addresses

The remote IP addresses in this list associated with a flow will be presented in the suspicious flow alert (previously activated).
