It is the first time that listening those abbreviations? You don't know what is dns and why he serves? Perhaps then your webpage takes with the thrown hand brake and for that reason it does not finish taking off, so you cannot lose everything to you what we will tell you on this subject in the next lines.

What is a servant dns?

We see how this concept defines Wikipedia:

The system of domain names (DNS, by its abbreviations in English, Domain Name System) is a system of hierarchic nomenclature decentralized for connected devices to networks IP as Internet or a private network. This system associates information varied with name of domain assigned to each one of the participants. Its more important function is “to translate” intelligible names for the people in associated binary identifiers with the equipment connected to the network, this in order to be able to locate and to direccionar these equipment world-wide.

A little muddied, truth? The truth is that he is much more simple that all that since what does a servant dns is, when you write a domain in your navigator, to associate it with the direction IP that corresponds to him.

Because he is simpler than you remember www.hostingguidebook.com that 178.33.117.119, no? For something you worried to choose the perfect domain for your Web!

How work does the service dns?

Just as the agenda of your mobile phone. When you want to call to somebody, unless you know his number of memory, you look for it in the agenda by its name and when beating, of automatic form your telephone dials its number.

Then the same it is the process that a servant only does dns that instead of phone numbers and people, handles to domains and directions IP. When you introduce the domain (that would be the name in the agenda) in your navigator, the servant of domains (that is to say your mobile) directs you to corresponding direction IP (the phone number). We see it with an example so that it is clear absolutely.

Pablo wants to make money with a Web and to lodge it in the best servers and to the best price, HostingGuideBook has recommended him, reason why our domain writes in its navigator. Then what it happens is the following thing:

  1. When introducing our direction, its navigating one sends to a signal to a servant dns so that it indicates our direction to him IP.
  2. When it finds the IP associated to the domain, one gives back the navigator of Pablo.
  3. Now that the navigator knows the IP to which he must go, accedes to her and shows the Web.

Easy, truth?
