Address Management is the process of maintaining and editing Domain Name Service (DNS) configurations. DNS ties text-based domain names to the numeric IP Addresses that are necessary to locate the domain's server on the net. Address Management solutions become necessary when:
An administrator needs to maintain many domain names.
An administrator needs to assign and track separate names for many machines within one domain.
A domain name changes IP address frequently, requiring Dynamic DNS (DDNS). This is most commonly used by individuals who connect their server to the internet using a modem.
