Domain Name System (DNS)

Categories: D, SEO Glossary

The Domain Name System (DNS) is a hierarchical naming protocol that translates human-friendly domain names into numerical IP addresses that computers use to locate and identify each other on the network. Essentially, it serves as the internet’s phone book, associating each domain name, such as a website’s URL, with a specific IP address, thereby enabling the correct routing of information and ensuring that users reach the correct online destination.
