# IP Whitelist

> Lock your API access to approved IP addresses only

<Note>
  In a nutshell<br />
  Blockradar's IP whitelisting lets you restrict API requests to specific IPs, adding an additional layer of protection to your integration.
</Note>

## How It Works

By default, your API key can be used from any IP address. With IP whitelisting enabled, Blockradar will reject any API request that doesn't originate from one of your approved IPs. This helps prevent unauthorized use of your API key, even if it's accidentally exposed.

## Setting Up IP Whitelisting

<Steps>
  <Step title="Go to Developers">
    Log in to the [Blockradar Dashboard](https://dashboard.blockradar.co) and navigate to the **Developers** page from the sidebar.

  </Step>

  <Step title="Open IP Whitelisting">
    Find the **Secure your API key with IP whitelisting** section.
  </Step>

  </Step>
</Steps>

<Warning>
  Make sure to add all IP addresses that your application uses to call the Blockradar API, including any staging or CI/CD servers. Requests from non-whitelisted IPs will be rejected.
</Warning>

<Tip>
  If you're unsure which IP your server uses, you can check by running `curl ifconfig.me` from your server's terminal.
