What service turns IP addresses into human-readable names?

The service that converts IP addresses into human-readable names is the Domain Name System (DNS). This system is essential for making the internet more user-friendly, as it allows users to access websites using easy-to-remember domain names instead of having to remember numerical IP addresses. For instance, instead of typing in a long string of numbers (like 192.168.1.1) to reach a website, users can simply enter a domain name (like www.example.com).

DNS operates like a phone directory for the internet, where it contains records that map domain names to their corresponding IP addresses. When a user types in a domain name, a DNS query is made to find the associated IP address, allowing the user's device to connect to the desired resource. This process greatly enhances the usability of the internet by making it accessible to the general public, who may not have the technical knowledge to work with numerical addresses.

Other options like HTML, FTP, and HTTP serve different purposes in web development and internet communication but do not play a role in translating IP addresses into human-readable names. HTML is a markup language used for creating web pages, FTP is a protocol used for transferring files between computers, and HTTP is the protocol used for transmitting web pages on the internet.
