Speed up & Secure your Internet Browsing and Access Blocked Sites in your School, College or Office with Google Public DNS
In this post I will tell you about how you can speed up and secure your Internet browsing significantly in both Windows and Linux and also access the blocked sites in your college with the help of free service – Google Public DNS
When it comes to Internet speed, every one wants it to be fast, isn’t it. A few days ago I posted how you can make your downloads faster in Linux and today I will tell you about how you can make your browsing faster in both Windows and Linux. For that you need to change your DNS servers to Google Public DNS. DNS servers? What are they?The thing is when you type a URL in your browser’s address bar, like www.google.com, it first get resolved to a 12 digit IP address as computers can only understand numbers, not any alphabets. This IP looks like 125.008.025.147 and each of the sub-addresses separated by dots ranges from zero to 255. This work of converting a alphabetic URL to its corresponding IP address is done by a DNS server (DNS means Domain Name Service). By default, your Internet service provider have their own DNS servers, but as many people use them, they may get jammed and resolving may be slow, thus slowing down your browsing experience. Google Public DNS is a free DNS server which you may use as an alternative to your ISP’s DNS servers. As Google bots crawl millions of web pages every day, they resolve the IP addresses and cache them, thus using Google Public DNS may significantly speed your browsing experience and also make it more secure and reliable.
Using Google Public DNS in Linux
When you are connected to the Internet, open the Network Settings and switch to your active connections tab. It will show you the current DNS information, if any.
Now open Network Connections option and select the tab of connection you use, e.g. Wired, Wireless, Mobile broadband etc. Open its settings and change the DNS servers to 184.108.40.206, 220.127.116.11. Save and exit.
