Host large live streams with less bandwidth using eCDN

Step 1: Enable private IP address discovery

Meet eCDN uses the browser’s JavaScript API to retrieve a device's private IP address. The private IP address of a device is usually hidden from the browser by a feature called mDNS. To enable eCDN, you have to turn off mDNS. 

Turn off mDNS safely

The mDNS feature is a security measure. We recommend you turn it off on a per-domain basis. That way, you only expose IP addresses to Google.

Check mDNS status

To check if Chrome for a device has a properly set mDNS policy:

  1. In any Chrome address bar, enter chrome://policy/ 
  2. Filter the policy list for WebRtcLocalIpsAllowedUrls.The policy should include meet.google.com
