Domain Name System (DNS) is a hierarchical naming system for computers, devices, or
any resources connected to a network. DNS is used to resolve hostnames into IP
addresses, and to enforce naming conventions for devices in the network and/or domain.
DNS configuration for devices can be either static – administrator configured – or acquired
dynamically through DHCP.
