What is DNS


DNS stands for domain name service. DNS allows your pc to translate a friendly computer name like http://indiatip.blogspot.com into numbers that our computer understands. So instead of the computer understanding  or www.google.com it will turn that into a unique IP address (Internet Protocol) like 24.33.24.112. Now the computer can take you there.
Every website has it’s own unique IP address and you can view this by using the PING command. See the screenshot below. I typed in ping www.google.com and then pressed enter. Now I can see Google’s IP address.

The average computer user has no idea that the domain names they use to get to websites are actually converted to IP addresses to allow computers and devices to reach their destination

  2. DNS means Domain Name System which helps to transfer ip address to domain name and domain name to ip addresses.It plays vital role in internet technology.For example,if you provide domain name like Google.com it convert the domain name into particular ip address.If you provide the ip address like 74.125.239.9 the domain name server will search for the particular website and display on your browser.DNS consist of many resource records.Some of them are A record,CNAME record,DNAME record etc., You can check domain to ip ,Ip to domain and DNS query using the site www.whoisxy.com
