The DNS make it possible to assign domain names in a meaningful way to Internet resources as well as users in a meaningful way, regardless of the entity's location. As a result, the WWWW hyperlinks (World Wide Web) will maintain its consistency and will stay constant even in the case of using a mobile device. Due to the fact that the Internet domain names are easier to keep track of as compared to IP addresses, this is an important advantage for the user because the computer will locate the URLs (Uniform Resource Locators) or even e-mail addresses the users may be looking for. | The DNS make it possible to assign domain names in a meaningful way to Internet resources as well as users in a meaningful way, regardless of the entity's location.

Coordination | Coordination across the Internet is maintained by means of a complex authoritative root system known as [[Top Level Domain]] ([[TLD]])DNS and other smaller name servers responsible with hosting individual domain information. For each domain, the DNS spreads the responsibility by mapping the domain names and assigning them into IP addresses, and vice-versa. This is accomplished through authoritative name servers which are being designated for each domain. Each authoritative name server is responsible for its own particular domain while having the authority to assign new authoritative name servers to any of their sub-domains. The DNS is able to store many types of information, even the mail server lists for a specific domain. In order to ensure the functionality of the Internet, the DNS is a core element through its distributed keyword-based redirection service. | ||
