DNS can be quite complicated if you over think it. When it comes to DNS, it is important to keep things simple.
For beginners, or those who have no idea about internet technology, its easiest to think of a DNS as a directory or telephone book. The directory (telephone book) translates the name of a person or business into an address/phone number, right?
This is exactly what DNS does for the internet. DNS (Domain Name System) translates the name of a computer (or other network equipment), into addresses, known as IP addresses.

When I type “host bamajr.com” into my linux terminal screen as so:
bamajr@9H38PJ1:~$ host bamajr.com
then press the [enter] key. I get the following output:
bamajr.com has address 22.214.171.124
…along with some other information.
In this example, typing “host” tells my computer I want to reference a DNS (or directory). The “bamajr.com” following “host” signifies I’m looking for the name “bamajr.com” in the DNS (or directory). When I press enter, a DNS finds the information I asked for and presents me with the information available for the name (bamajr.com) I requested. In this case, “126.96.36.199” is the IP address (or address) on record.
See, this stuff isn’t so difficult, right?
I mentioned before that keeping things simple, would make it easier to understand and I hope I’ve been able to help you in your understanding of DNS, by keeping things simple for you.
