Abstract:
Using DNS communications to filter domain names is disclosed. A domain name is extracted from a received DNS request. The received DNS request is blocked in response to determining based on a policy that access to the domain name of the DNS request is not permitted. In some cases, such a DNS request is responded to with a spoofed DNS response.
