Domain Name Service (DNS)
Domain Name Service (DNS) is a public service by which Internet domain names are translated into IP addresses. Domain Name Service lookups of domain names to get addresses is called forward DNS lookup. Domain Name Service can also translate IP addresses into domain names. Domain Name Service lookups of IP addresses to get domain names is called reverse DNS lookup. The Domain Name Service (DNS) protocol provides this necessary domain name lookup function because we humans have trouble remembering numerical IP addresses, so we let the computers running Domain Name Service perform the domain name lookup, changing the domain names we CAN remember into the IP addressees computers need to communicate.
