Google enhances security for your website look-ups

March 20, 2013

Google has fully implemented a security feature that ensures a person looking up a website isn't inadvertently directed to a fake one. The Internet company has run its own free public Domain Name System (DNS) lookup service, called Public DNS, since 2009.

In an attack called "cache poisoning," a DNS server is hacked and modified so that a user looking for www.idg.com is directed to a different website.
