How to Change DNS – Guide


A very useful resource in order to speed up the Internet connection, and therefore the display of Internet pages can, nowadays, be made by optimizing the TCP protocol / IP (See TCP / optimizer program) or by changing the DNS addresses. (very simple procedure that gives a remarkable achievement)

Domain Name System (DNS often referred to) is a system used to resolve host names into IP addresses and vice versa. The service is provided through a distributed database consisting of the DNS server. The DNS name also denotes the protocol that governs the operation of the service, the programs that implement it, the servers on which they run, all these servers cooperating to provide the service.

DNS names, or “domain names”, are one of the most visible features of the Internet.

This brings with it the browsing speed? Simple! whenever the computer queries a DNS server there is a latent period of the response, especially if the DNS server is overloaded due to many requests, causing a slowdown in navigation!

Now, we must also say that every provider gives their dns servers available to its users, despite this slowdowns happen … Also we point out that there are also free services to Open DNS on the network including Google (whose DNS is 8.8.8.8 or 8.8.4.4) (very fast no doubt);)

to remedy this, you can change the settings of your router or pC to the dNS entry in the TCP / iP settings by entering other more rapid dNS addresses.

There is an excellent program to test the DNS is called Namebench, I downloaded and installed. On the main screen you will see the DNS addresses that your PC is using,
