Steps to add Open DNS in Ubuntu Linux

Today I faced some DNS issues with my new computer after installing Ubuntu in it. After some basic troubleshooting steps I assigned Open DNS address to my network adapter and the issue is resolved. Open DNS is a smart way to make our browsing fast and reliable. As the name suggests this DNS service is absolutely free and worth a try. Before go to open DNS we need to know a little bit about DNS. As we know DNS is used to convert the domain name of of website to its IP address. For any communication your computer should know the mac address and IP address of the destination (Here web server). MAC address can be obtained from ARP table and if the user type the IP address of the web server computer knows both. If the user type the domain name of the website your computer don't know the IP address of the destination and the communication will not happen. Here the DNS server helps. DNS helps to resolve the domain name to IP convertion issue and send the destination IP address to the computer.


So it is understood that every computer which connects to the Internet should know the DNS server address. There are many DNS servers available including your ISP's DNS server. Here I am presenting the steps to assign Open DNS in Ubuntu linux.
