When it comes to the design and maintenance of IT infrastructure, the Domain Name System (DNS) tends to be ruefully ignored. DNS servers are an important part of the internet backbone; once these servers fail, everything else seems to crumble.
That stands for Domain Name System. Internet users do not have to be able to define the term in order to use it. It is enough to know that this is how Internet surfers are able to reach websites using popular names. In fact, everything reachable on the Internet must have a numeric address, i.e., IP address, and Internet spaces are reachable only at their IP address location. However, who would ever remember or ever use 184.108.40.206 in order to reach Google? No one could, nor does anyone need to. Fortunately, wizards of DNS abound. Skills and techniques are being advanced by the day. The domain name system is only getting better and more useful. The domainn name system provides the valuable service of translating Google.com into 220.127.116.11 so that the Google website is reachable with that catchy website name Google.com.
When setting up publicly available web servers, many things must be configured correctly for everything to work smoothly: firewall settings, choosing the appropriate user account controls, and installing updated and patched versions of the web server of your choice. However, one of the least transparent steps of the process is configuring the DNS settings for your server.
