Nominum to offer DNS 'blacklist' capability

Nominum plans to announce today a novel DNS security capability that functions like a spam blacklist, providing automated, real-time checking of DNS queries against a list of Web sites that are known to be malicious.

Nominum's Trusted Response and Universal Enforcement (TRUE) architecture is already in use by several ISPs supporting a combined 100 million broadband households. Nominum wouldn't identify these ISPs, but its Web site says its carrier customers include Verizon, Sprint, NTT Communications and other major industry players.

Now Nominum is making its third-generation DNS software that features the TRUE architecture available to corporations and other enterprise customers.
