Find your PoP

Every response from Bunny CDN includes a Server header that identifies which PoP and server handled the request: 
Server: BunnyCDN-{PoP Code}-{Server-ID}
To find this header:
  1. Open your browser developer tools (Ctrl + Shift + I or Cmd + Option + I)
  2. Go to the Network tab
  3. Load a URL from your Pull Zone
  4. Click on the request and find the Server header in the response headers
Alternative: Use the Bunny Diagnostic Tool to automatically show your connection details and PoP routing.

​
Detect CDN requests on your origin

When Bunny CDN fetches content from your origin, it includes identifying headers you can use for whitelisting or custom logic:
HeaderValue
CDN-ServerIdInternal server ID
ViaBunnyCDN

​
Other detection methods

Custom hostname: Use a unique, hard-to-guess hostname as your Origin URL that only Bunny servers access. Edge Server IP list: Whitelist CDN IPs programmatically:
  • IPv4: https://bunnycdn.com/api/system/edgeserverlist
  • IPv6: https://bunnycdn.com/api/system/edgeserverlist/IPv6
CDN IPs can change. Automate IP list updates to prevent connectivity issues.
Custom header via Edge Rules: Add a secret header in Edge Rules that your origin validates for authentication.
