Which acronym is used for translating domain names into IP addresses?

• A. DLS
• B. DNP
• C. DNS
• D. DPH

Answer: (C)

Translating domain names into IP addresses is the job of the Domain Name System. Humans remember names like example.com, but networks route by numeric IP addresses. DNS acts as a distributed directory that maps those readable names to the corresponding IPs so browsers can reach the correct servers. When you enter a domain, your device asks a DNS resolver to find the IP. The resolver may check its cache, then query root servers, then top-level domain servers, and finally the authoritative server for the domain to obtain the IP, which is returned so the connection can proceed. DNS also caches lookups to speed up subsequent requests. The acronym used for this translation is DNS. The other acronyms listed aren’t related to this function.
