So, what is a DNS name server? A DNS name server is essentially a computer that maintains a database of domain names and the corresponding IP addresses. When someone Googles “www.google.com,” their computer queries a DNS name server for the IP address for “www.

google.com.” The name server then responds with the IP address for Google’s website.

DNS name servers are also used to resolve hostnames to IP addresses. Imagine you are hosting a website on your computer and you want people to be able to access it from anywhere in the world. You would need to give your website a hostname, like “www.mywebsite.” But, you don’t want people to be able to type in the hostname and get the IP address for your website.

You would instead want them to type in the domain name, like “www.” Your DNS name server would then look up “www.com” in its database and return the IP address for the website.
