Abstract
A packet containing a request for content is initially received at a content filtering router. The packet comprises a first destination Internet Protocol (IP) address of a content server that stores the content and a second destination IP address of the content filtering router. It is then ascertained that the first IP address is on a list of destination IP addresses to be filtered and the packet is, therefore, routed someplace other than the first destination IP address, such as to a port that discards the packet.
