Abstract
A host name query is received by a modem from a client computer. The host name query is simultaneously transmitted from the modem to a plurality of Domain Name System (DNS) servers. A response is returned to the client computer from the modem, where the response is based on the host name query and any responses received from the DNS servers. In a preferred embodiment at least one address associated with the host name query is acquired from the DNS servers. The client computer then sends a request for content to the address. If more than one address is returned, all but one of the addresses is eliminated. This can be done by rejecting all but the most recent address, or rejecting all addresses not provided by a service provider DNS server.
