# Medianova IP Blocks

Obtain Medianova’s CDN IP address ranges for firewall allowlisting.

Medianova’s CDN uses specific IP address ranges to fetch content from your origin servers.\
If your origin server uses a firewall or IP-based access controls, you **must allow all addresses listed below** to ensure reliable access from Medianova edge servers.\
This allows the CDN to retrieve and deliver your content securely and efficiently.

#### Available Formats

<table><thead><tr><th width="109.00006103515625">Format</th><th width="221" align="center">URL</th><th>Description</th></tr></thead><tbody><tr><td><strong>JSON</strong></td><td align="center"><a href="https://cloud.medianova.com/api/v1/ip/blocks-list">Medianova CDN IP ranges (JSON)</a></td><td>Structured format with separate IPv4 and IPv6 lists. Useful for automation and API integrations.</td></tr><tr><td><strong>Plain Text</strong></td><td align="center"><a href="https://cloud.medianova.com/api/v1/ip/addresses-txt">Medianova CDN IP ranges (Text)</a></td><td>Simple text file where each IP block is listed on a separate line.

{% hint style="warning" %}
Only allow traffic from Medianova’s IP ranges to reach your origin server (block all other sources). This practice secures your origin by preventing direct attacks and bypass attempts. Also ensure you include every address (both IPv4 and IPv6) in the allowlist. If any Medianova IP is omitted or blocked, the CDN cannot retrieve content from your origin.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://clients.medianova.com/products/performance-cdn/static-content-delivery/configuration-basics/medianova-ip-blocks.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
