Which technology is responsible for resolving a host name to an IP address?

The Domain Name System (DNS) acts as the internet's phonebook, allowing users to access websites and other network resources by using memorable hostnames like example.com, which it translates into the IP addresses necessary for computers to locate and communicate with each other on a network.

SNMP (Simple Network Management Protocol) is used for managing and monitoring network devices, not for hostname resolution.

DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses and other network configuration parameters to devices on a network, but it does not resolve hostnames to IP addresses.

NTP (Network Time Protocol) is used for synchronizing the clocks of computer systems, which is unrelated to hostname to IP address resolution.
