Domain Name Service
Overview
Domain Name Service, commonly known as the DNS, is defined as a naming system for computers, services, or resources which deal with Internet or a private network. The DNS interprets domain names and converts them into a numerical (binary) identifier, which can be identified by the computer. These numerical identifiers are known as Internet Protocol (IP) addresses.
Names are easy for people to understand, while computers understand numbers. So, when we use names to identify websites, the computer can process the data only if it is in the form of a numerical. DNS also allocates a domain name to a particular website. This allocation is not based on the physical location of the user. This is because World Wide Web hyperlinks and Internet contact information are stable and do not change even if there are changes in routers.
Benefits
There are four major benefits offered by Domain Name Service. They are free manage DNS service, free domain forwarding, low cost, and security. Free manage DNS services allow you to have control over the whole domain. All the domains and associated domains are managed by DNS records through its reliable infrastructure and automatic updates. You can hide the destination URL in any domain using free domain forwarding feature. It is done by URL masking. By doing this, your URLs remain hidden from the surfer and your brand identity remains consistent, providing an enhanced performance. The costs of DNS are low and affordable. DNS offers security and protects your website from hackers. Apart from these benefits, domain name system also has various services like mail servers that accept e-mail for Internet domain.
How It Works
The DNS assigns a particular IP number for every domain name, which is unique. A particular domain name can be divided into three levels. The first level indicates the name of the website like "Example," the second level mentions the domain of your website. It could be .COM, .ORG, or.EDU. The third level refers to the country like, .US for US websites, .UK for UK websites, or .AU for Australian websites. So, the domain name of your website could be "www.example.co.us." DNS then allocates a particular IP address for this domain name. All the names and IP addresses of domain names are maintained by a company called Network Solutions.
The DNS accepts request to convert domain names into IP addresses, both from programs and other servers. When you type in a URL into your browser, it first converts the domain name into an IP address. To do this, the browser contacts the DNS, which retrieves the right IP address for the webpage that you have requested for. The browser then recovers the right webpage corresponding to the IP number and displays it on your system.
Companies/Brands
Web hosting companies also offer domain name registration services. Companies such as International Corporation for Assigned Names and Numbers (ICANN,) Veri Sign, and Inter NIC offer domain name services.
