ABSTRACT:
A packet containing a request for content is initially received at a content filtering router. The packet comprises a destination Internet Protocol (IP) address of a content server that stores the content and a bogus IP address. It is ascertained that the destination IP address is on a list of approved destination IP address. Alternatively, it is ascertained that the destination IP address is on a list of probably unapproved destination IP addresses and the packet is routed in accordance with an alternative IP address to a content filtering server. In this alternative, at the content filtering server the bogus IP address is used to determine a content filtering category and it is ascertained whether the destination IP address with the content filtering category should be filtered based upon a list of IP addresses and associated content filtering categories.
