A DNS domain list is a collection or list of domain names associated with a DNS (Domain Name System). Domain lists can be used to control access to specific domains, either by allowing or denying requests to those domains.

DNS domain lists can enforce various policies, such as security policies to block access to certain domains. They also enable organizations to monitor and log DNS queries for specific domains, helping in network management and security.

One or more domain lists can be used with DNS traffic rules to deny the resolution of malicious or undesirable domains
