DNS or Domain Name Service provides the translation of an Internet address that we usually enter in the browser, for example http://www.lejinternetplaza.com to an IP address in this case 220.127.116.11. You can compare it with a telephone number that you use to connect so someone. DNS translates a number into a word because people can remember easier a name instead of numbers. If a DNS is not working you can’t connect to a website because you don’t know the address. And even then, many websites sharing the IP address so they expect you that you use the IP address and also the name of the website. You can compare this with making a phone call to someone, and that telephone is shared with more people in the family and you can ask the person you want to talk.
