Thus, when you type into a Web browser’s URL field, rather than your computer receiving back the correct IP address from its built-in DNS resolver – 216.168.61.78, in this case – an attacker would indirectly convince that resolver to believe the address was something else, like 172.31.0.16. (This is called cache poisoning.) The attack doesn’t affect the DNS server software – it doesn’t compromise the software itself – but rather the attack changes the information the server stores, or caches, to provide answers about domain names that the server has retrieved from elsewhere. Poisoning the DNS Well - Kaminsky accidentally discovered a new technique attackers could use to compromise DNS servers, allowing ne’er-do-wells to convince servers to accept an incorrect IP address for a given domain name from a source other than the one that properly controls information for that particular domain.
