Domain Name System and DHCP
Network addressing is facilitated by automated systems that translate identities and configure host parameters.
The Domain Name System (DNS) functions as the directory or "phone book" of the Internet. It translates human-readable hostnames, such as example.com, into the numeric IP addresses required by computers to route packets.
The Dynamic Host Configuration Protocol (DHCP) automates network setup by assigning an IP address to a device automatically when it connects to a network, removing the need for manual configuration.
