A DNS cache sometimes called a DNS resolver cache is a temporary database maintained by a computers operating system that contains records of all the recent visits and attempted visits to websites and other internet domains. Cache poisoning is an attack vector that exploits the way domain name system DNS clients and web servers improve performance by saving old responses for a specified period of time in a temporary storage area called cache. Typically such caching DNS servers also implement the recursive algorithm necessary to resolve a given name starting with the DNS root through to the authoritative name servers of the queried.

One of the reasons DNS poisoning is so dangerous is because it can spread from DNS server to DNS server. Occasionally a cache may become corrupted because of technical glitches or administrative accidents but DNS cache poisoning is typically associated with computer viruses or other network attacks that insert invalid DNS entries into the cache. Domain Name System DNS Cache Poisoning DNS cache poisoning also known as DNS spoofing throws a theoretical wrench in the process of translating an internet protocol to a domain name and sending the client to the preferred site.

Poisoned DNS caches DNS poisoning occurs when one of these caches is compromised. IP addresses are the room numbers of the Internet enabling web traffic to arrive in the right places.
