'''DNS spoofing''', also referred to as '''DNS cache poisoning''', is a form of computer security [[Security hacker|hacking]] in which corrupt [[Domain Name System]] data is introduced into the [[DNS resolver]]'s [[DNS cache|cache]], causing the [[name server]] to return an incorrect result record, e.g. an [[IP address]]. This results in [[Man-in-the-middle attack|traffic being diverted]] to any computer that the attacker chooses. Put simply, a hacker makes the device think it is connecting to the chosen website, when in reality, it is redirected to a different website by altering the [[IP address]] associated with the [[domain name]] in the DNS server.<ref>Hanley, Sinéad (2000-11-06).
