Patent abstract
A method for controlling access to information from a DNS server having an access control list specifying clients approved to receive an IP address corresponding to a domain name of a target host is disclosed. The method includes receiving a request from a client for an IP address of a domain name at the DNS server and looking up the domain name in an access control list. The client is sent a reply containing the IP address of the domain name if the client is authorized in the access control list to receive the IP address. If the client is not authorized to receive the IP address, the request is denied.
