How can computers on a local network contact an antivirus update server hosted on a dynamic content delivery network?

The selection of configuring a policy to allow outbound requests to the wildcard Fully Qualified Domain Name (FQDN) of the antivirus updates is the most effective method for enabling computers on a local network to access an antivirus update server hosted on a dynamic content delivery network.

Dynamic content delivery networks often use multiple IP addresses and servers to distribute traffic and provide redundancy and speed. Since the IP addresses can change frequently, using a wildcard FQDN allows the local network to connect to any of the servers associated with the antivirus update supplier without needing constant reconfiguration as the underlying IP addresses change. This method facilitates seamless and efficient communication, ensuring that devices can automatically connect to the correct server regardless of how the content is distributed.

Using policies that tie access to a specific IP range or involve making exceptions for HTTP requests may not account for the dynamic nature of the delivery network, where the server's actual address may vary, leading to potential connectivity issues and disruptions in receiving updates.
