The abbreviated term DNS represents what is known in the full form as Domain Name System/Server/Service. It is the means by which people communicate on the Internet using names rather than IP addresses. Internet protocol addresses are based on numerical numbers ranging from 0.0.0.0 to 255.255.255.255. This could be confusing considering the number of sites we visit in a day, as well as the number of people we communicated with via the Internet.
To make web commuting and communication simpler the IP address is converted into a domain name. For instance, a numerical IP address xxxx.xxxx.xxxx.xxxx could be converted to the domain name, domainname.com. Imagine having to remember multiple IP addresses… too much for the normal human brain.
DNS functions as a database. It is largest database that exists in any given form, and the most active of all databases. Every day, there are millions of people across the globe who visit web domains for various reasons, and there are people creating new domain names every day.
Yet in spite of this infinite networking, the domain server providers have a proper system in place, converting DNS addresses to IP addresses, thereby making web pages available to everyone. The fact is that the website names and email addresses are all a part of the DNS.
In spite of the fact that there are millions of domain names already registered, the entire system is set up in a way that at no point can the same domain name be provided to any two persons anywhere in the world. It is a system that within seconds can tell you whether your requested domain name already exists or not.
To get your DNS registered you need to apply with a domain name provider. There are many IT companies that purchase domain names and then sell them to people wishing to set up their website. There are some domain names that can be given free of cost, whereas others are auctioned. If you want to set up a website, you need to apply for a domain name to be attached to the DNS.
