# IP Whitelisting

#### **How to Enable IP Whitelisting**

To manage your IP whitelist, go to your proxy settings and click **Modify** under the **IP Whitelist** section.

From there, you can add or update the authorized IP address linked to your plan.

{% hint style="info" %}
IP whitelist authentication is currently unavailable on the Per-GB Residential plan.  This feature is available on the Unlimited Residential plan.
{% endhint %}

**Default Limit**

By default, ISP plans include **1 whitelisted IP**.

This means you can authorize one IPv4 address to access your proxies without using credentials.

**Adding More IPs**

If you need more whitelisted IPs, you have the following option:

* Upgrade your plan to include up to 2 additional IPs

If you require more than the available upgrade options, please contact our team through the live chat to request a custom quote.
