Domain Name System Response Policy Zone(DNS RPZ)
A file that identifies domain names that are known (or suspected) to resolve to Internet Protocol (IP) addresses that host botnet command-and-control servers or other malicious content.
Zone administrators in the DNS deploy RPZs to create firewalls around their recursive resolvers. The resolvers check the RPZ when they receive requests to resolve domain names. If a requested domain appears in the RPZ, the resolver can return an error message or redirect the requestor to a web page that provides malware detection and remediation instructions.
