Google announced the launch of Google Public DNS own, and submitted for use by all users free of charge.
What is the DNS?
In the mobile device you have, when you want to call your friend, click on his name only, and then the connection is made. Bhsal which is that the numbers on your mobile device does not bring the name (script) for the mobile network, instead, directs the caller ID because they know that this name is linked to that figure.
This is exactly the DNS and what he does. He knows that the name of the site which was written by a particular IP number tied flies to its own server, and then displays its contents on the computer screen in front of you. If it works as a database of names and numbers of names in our equipment such as phones.
For example, when you write swalif.net in your browser, passes the request through the DNS, which in turn by the IP to any number back, and thus access to the right server for the site you requested, and to bring its contents and then display the computer screen in front of you.
How is the query as soon as I entered the internet?
Without the need to enter into technical details, it is when you connect to the Internet as follows:
When you connect to the Internet, the Internet Service Provider you have flags (supply) your PC number of its DNS automatically generate -> you are typing the address of a site to go to -> The browser you convert the caption text that you typed to the server’s DNS service provider Online you have to know any IP number back -> the browser after seeing the figure to go to your server and retrieve the contents of the site and display it on the screen of your PC
Warning!
Should be the DNS system, which are using a reliable and secure. Why? Did you see that you typed in red above? This means that systems can DNS unreliable, should refer you for example when requesting the Bank to another server does not belong to the bank, and when the page identical to the banking page which is used to see, and thus entering your account information without knowing that they were another page in another server do not have relationship bank!
So, what did Google and what Google Public DNS?
Seems to be Qoukl not convinced the performance of the current DNS system, and see that it does not deal with requests that we do every day in a smart and fast. Qoukl says that the current DNS systems are due to the many query operations that we have by us and others to convert it, compress the cause of the delay in passing a number of our requests, and delay in the Internet browser to see which sites ask.
From here emerged the draft Google Public DNS, which says Qoukl him as one of the fruits of their interest in promoting fast website. Appear to be interested in speed to the point of starting from the first point have involved, the query point as soon as we asked for one of the sites, before moving on to speed servers themselves after that, and Internet connection speed.
Google says that Google Public DNS better than the current DNS systems in the following:
* Faster in the requests for information (knowledge of each name, to any number back IP), a feature which plays the most important role the difference here
* Best in the storage system Caching
* Safer and less vulnerable to sabotage
