The Domain Name System (DNS) serves as the main means of giving names to entities on the Internet. Now over 25 years old, its original goal was to provide a way to consistently map host names to IP addresses. Since then, DNS has grown to identify the Internet presence of brands, companies, products, political campaigns, and individuals. Compared to other means of navigating the Internet, DNS has a very rigid lookup structure: a user must know the name precisely and completely in order to perform a lookup.
