👉 I'll explain it in English. "4440.conf" is a term referring to the name of the server where you can find an external DNS server for Google Cloud CDN. The code snippet `4440.conf` specifies the domain you wish to serve your content from. The 'conf' part indicates that it's a configuration file, and the '4440' refers to the IP address assigned to the server named 4440 in the Google Cloud DNS cluster. For instance, if you have an external DNS service with the name `google.com` hosted at `10.2.8.5`, `4440.conf` would point your domain to `google.com`.
