How the Domain Name System Works: Difference between revisions

Line 13:

The DNS makes it possible to assign domain names in a meaningful way to Internet resources as well as to users, regardless of the entity's location. As a result, the WWW hyperlinks remain consistent, even for mobile devices. A domain name is an easy way to remember an address, but that needs to be converted to its numerical, IP format. <ref>[http://www.modemhelp.net/faqs/dns.shtml About DNS]</ref>

Coordination across the Internet is maintained by means of a complex authoritative root system known as the [[TLD|Top Level Domain]], as well as the DNS and other smaller name servers responsible for 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 have been designated for each domain. Each authoritative name server is responsible for its own particular domain, but it has the authority to assign new authoritative name servers to any of its sub-domains. The DNS is able to store many types of information, even the mail server lists for a specific domain. The DNS is a core element which ensures the functionality of the Internet through its distributed keyword-based redirection service.

However, the DNS does not include security extensions, which was instead developed as [[DNSSEC]].
