What is DNS?

In simple terms, we could describe a DNS as a domain address book. Just like you would use an address book to look up information related to a particular person or company by name, the same goes for domains, since they also have an “address”. When you type our address mydataknox.com in your browser, your computer uses DNS to retrieve the data about the IP addresses linked to our domain. Afterwards, your computer requests the IP address of our web server, which, finally, sends the web page to your browser.
To summarise, DNS connects symbolic domain names, such as the mydatakno.com domain, with the IP address of the server where the domain-related content is located.
