# IP Whitelist Management

IP whitelisting allows you to authenticate proxy access by linking a client’s IP address directly to a specific user account — ensuring secure and controlled usage without requiring username and password login. This method is commonly used when integrating proxies into browser extensions, automation tools, or server-side applications.

Currently, only **IPv4 addresses** are supported.

Each account can add up to 20 IP addresses to the whitelist. If you need a higher limit, please contact our support team.

**Please note** :&#x20;

* Each IP address can only be bound to one account at a time. You can add it once it’s removed from another account’s whitelist.
* **Mainland China IPs** cannot be used with our services due to regional restrictions and therefore cannot be added to the whitelist.
* The whitelist authentication method is not available for Unlimited Plans.
