# Whitelisting IP Addresses If your network restricts access by IP address (for example, corporate firewalls, VPNs, or private APIs), you may need to **whitelist Adalo’s IP ranges** to ensure all services function correctly including app builds, API calls, and external integrations. #### 📡 Adalo IP Address Ranges Our data centers use the following IP ranges. Your organization may need to whitelist them to ensure uninterrupted communication between your systems and Adalo: ``` 66.151.48.0/22 66.45.80.0/22 66.71.204.0/22 ``` These ranges may be used dynamically across Adalo infrastructure, so it is important to include the full block when whitelisting rather than individual IPs. #### 🧠 Why Whitelisting Is Important Whitelisting these ranges helps ensure * API calls are not blocked by your firewall * Adalo’s servers can communicate with your backend or authentication systems * Your app remains stable when network restrictions are applied If you use a managed hosting or corporate IT setup, share this list with your **IT or security administrator** so they can update their configuration. --- # 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://help.adalo.com/integrations/whitelisting-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.
