The DNS (Domain Name System), using a quick definition, are systems designed to "translate" the IP addresses of various websites and various Internet services to hostnames and vice versa, they are located all over the world and each provider typically provides its own. Normally, the DNS servers are automatically assigned to your PC, a router or other device used to connect to the Internet (such as a Smartphone) when the connection is established via ADSL, ISDN, 56K, etc.

I would like to explain you how to change the default DNS server with others, for various purposes.

For windows XP

Open the Control Panel double click on Network Connections.

In the list of network connections to identify the one which you want to change the configuration of DNS servers, click the right mouse button on it and select Properties, open the window in the central list identifying the item Internet Protocol TCP/IP, select it with click the left mouse button and click properties.

This opens another window where you can change IP address and DNS server, in this case are varied with the default DNS servers specified manually, simply click the Use the following DNS server addresses and specify the desired ones, the image sample uses the public DNS provided by Google.

Confirm the settings by clicking the OK button to close the window, in the next window click Close, and DNS servers are now set those manually and automatically assigned by the ISP will be ignored.

Change the DNS addresses on the router

If you have a multi-router, it is best to enter data directly into your OpenDNS settings panel. There are a lot of routers, and although OpenDNS offers tutorials for the most popular brands, there's always one escape. In general, follow these steps:

Access the router's control panel. You can reach it with the browser, typing the address of your gateway (usually 192.168.0.1 or 172.168.0.1). If you do not know your address, open command prompt and run ipconfig.

It will ask you to enter a username and password. Where not know must test the manufacturer. In RouterPasswords.com there is a huge list of logins for each manufacturer of routers. Once inside, find the page with the data configuration of DNS servers. Configuration panels usually have a related structure. Approximately always find a section in a submenu called DNS WAN, DHCP or Advanced. When you see fields for primary and secondary DNS, put the OpenDNS: 208.67.222.222 and 208.67.220.220. Somewhere there will be a button to save changes. Rarely need to restart the router.

Why change the DNS on the router? Useful if you have your desktop or you like to use DHCP to connect to the network. Leaving the router stores the addresses of name servers, you will save irritate of changing settings on your computer.

What does OpenDNS means?

OpenDNS is a free service of solving DNS per consumers and businesses as an alternative to using the DNS servers of their Internet Service Provider. Placing the assistants of the company in strategic locations and employing a large cache of the Domain Name, DNS requests are processed usually much faster, thereby increasing the speed of recovery of the page. The results of application of DNS sometimes are hidden by the operating system and/or by local application, so this increase in speed cannot be significant with each request, but only with the requests that are not stored in a local cache.

Why to use OpenDNS?

OpenDNS can provide a better return on our Internet browsing because the DNS servers of this company are designed and located geographically so that they can give a lower response time to requests for solving IP's to surf the net, I mean: All web servers have an IP address plus a web domain, IP addresses are used more now have the form "192,168,113,124". Domains are created precisely so that the user does not have to remember this series of numbers to enter a website, but could remember (which is much easier) a name in a language we understand, for example "xyz1234.com" what the DNS servers is to link these two things, the IP address with the domain so that when users type in the domain in your browser, the DNS server can resolve it and point at the server with the IP address to which it corresponds.

The advantage of using OpenDNS and not the default DNS server of our ISP is that OpenDNS is principally engaged in this, which the time resolution of IP's are optimized, so the faster you will access to websites. Another great advantage of using this service is that it has "spell check" as it were in some way, this means that if you type a web address incorrectly, we break down the OpenDNS site that is trying to access, for example if I type www.xyz1234. cm as will access this website.

There are many other public DNS servers, including Google, do not say that the others are wrong or that better, I recommend OpenDNS only.
