Which DNS resolution method translates a hostname into an IP address?

Reverse DNS
Forward lookup
Local name resolution
Zone transfer

The correct answer is: Forward lookup

The method that translates a hostname into an IP address is known as a forward lookup. This process is critical in the Domain Name System (DNS) as it allows systems and users to connect with devices on a network by their user-friendly names rather than having to memorize numerical IP addresses. When a forward lookup is performed, the DNS resolver queries the DNS server for the corresponding IP address associated with a specified hostname. For example, if you type "www.example.com" into a web browser, the forward lookup process will resolve this hostname to its associated IP address, enabling the user's computer to establish a connection to the web server hosting the site. Reverse DNS, on the other hand, does the opposite by translating an IP address back into its corresponding hostname. Local name resolution refers to methods where hostname resolution can occur within local configurations, but it's not a DNS method per se. A zone transfer is a process of transferring data from a primary DNS server to a secondary DNS server, ensuring both servers have the same domain records, and does not involve resolving hostnames to IP addresses.
