Profile Network Configuration
Domain Naming System (DNS) is a hierarchical naming system for resources connected to the Internet or a private network.
Primarily, DNS resources translate domain names into IP addresses. If one DNS server does not know how to translate a
particular domain name, it asks another one until the correct IP address is returned. DNS enables access to resources using
human friendly notations. DNS converts human friendly domain names into notations used by different networking equipment
for locating resources.
As a resource is accessed (using human-friendly hostnames), it's possible to access the resource even if the underlying machine
friendly notation name changes. Without DNS, in the simplest terms, you would need to remember a series of numbers
(123.123.123.123) instead of an easy to remember domain name (www.domainname.com).
