Firefox Network ID

In the Mozilla forum for firefox it was described that a Network ID telemetry is required for DNS over Https. When about:networking#networkid is entered in the URL of firefox a large alpha numeric value is displayed.

I use cloudflare D.O.H. and do not see how this value is associated with DOH. Does anyone have an explanation?


I am looking on a confirmation that Firefox Network ID is required and if so all D.O.H. browsers must have this value.
