# IP Address Filtering

Aerofiler offers the ability to add an allowed IP address range. To begin, go to Settings -> Organization -> Configuration

Go to the area for "Allowed IP Adress Ranges":

Add any IP addresses that you wish to specifically allow. For example, to specifically add the IP address of 59.101.13.70, you would add the following:

IP addresses can be added in CIDR Notation.

{% hint style="info" %}
Your IP address must be included in the IP address range.
{% endhint %}

Once the setting is saved, users outside the allowed IP address range will see a "Forbidden" error message when they try to access your instance.
