# Medianova IP Blocks

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.

{% 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.
