# Whitelist MessageBird's IP addresses If you are looking to whitelist MessageBird's IP addresses to connect your application to MessageBird's REST API because of your application's requirement, it will not be possible to whitelist the IP range for our REST API since our IP addresses are dynamic. Our REST API platform is offered from a globally distributed infrastructure. Hence you will not be able to whitelist the IP addresses of our platform. However, we do offer the possibility of using a signing key to verify HTTP requests. You can create a signing key via the [Developers window](https://dashboard.messagebird.com/en/developers/settings) → *API settings*. You can find more information on how to implement it into your API setup by checking our [Verify HTTP request](https://developers.messagebird.com/docs/verify-http-requests) Documentation. If you have any issues with this, please [reach out to our Support team](https://www.messagebird.com/contact) for further help! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.bird.com/connectivity-platform/troubleshooting/whitelist-messagebirds-ip-addresses.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
