What is DNS?
Written by Richi González Saturday, 3 March 2012
I’ve been reading a couple of articles here at Arvixe about DNS, but none of them explains what DNS actually is. I’ve worked with lots of things related to DNS, but if I had been asked like a week ago for a correct definition of DNS, I wouldn’t have had it. Today, I will provide you with the knowledge I have acquired, so you can understand what DNS actually is.
DNS, stands for Domain Name System. What it does, is to convert, whenever you type a domain name in your browser, to its IP address. In an easier to understand example:
Whenever you type: www.arvixe.com, DNS’s job, is to convert that domain name to the IP address assigned as the location of that domain name. Therefore, it’d be converted to 126.96.36.199, which is an IPv4 address.
What are the advantages of DNS?
The most important, for me, is that it is easier to remember a domain name rather than an IP address. Don’t you think? It’s way easier to remember arvixe.com, than 188.8.131.52.
The next great advantage is that if for some reason the server changes IP address or the site has been moved to some other place, the domain name would work, while the original IP would not.
And that’s pretty much the functionality and importance of DNS. I hope you now have a better idea now of what DNS is. If you have any comments, questions, or suggestions, please write a comment below and I’d be more than glad to assist you.
