How to Install DNS in Windows Server 2012 R2

In this article, we’ll learn the steps to install DNS in Windows Server 2012 R2. It is used to translate Domain Name into IP address and IP address into domain name. AD Integrated DNS would get installed and configured automatically when you are promoting a Domain Controller. However you can still have DNS in your environment even if you don’t have Domain Controller in your environment.

Why do we need DNS Server?

Before I explain about DNS, let me ask you about Google. How many of you have visited Google.com, I hope everyone. Next questions is, how often do you visit Google.com. Some of us visit once in day, twice in a day or multiple times in a day. Now the next question, do you know the IP address of Google.com?. No problem if you don’t know the IP address of Google, you can tell me an IP address of Facebook.

That’s ok, if you don’t know IP address of Google or Facebook or don’t remember them because human mind is capable of remembering names however remembering IPs or numbers is difficult. Alternatively, computers only understand IPs i.e. numbers and not names. Therefore, Domain Name System comes into the picture. It keeps record of all the domains and map hostname to IP address. When you type Google.com in your browser, DNS converts this name to an IP address and then communicate with Google. Hope your understanding is clear now.

Let’s begin with the steps to install DNS in Windows Server 2012 R2
