ABSTRACT:
A device and method filter information to restrict access to private information of a domain in a domain name system. The device includes a filtering device. The filtering device filters information received from devices external to the domain by removing the private information before forwarding the information to devices within the domain. The private information includes IP addresses and domain names. The private information also includes any additional information appended to legitimate responses to requests from devices in the domain.
