Domain Name System in Computer Networks

The primary element in the Domain Name System (DNS) is a huge collection of DNS servers. The server is any computation registered jack that adjoins the DNS. It mans on special-purpose network software, basically featuring a widely used IP address as well as being the storage database for network labels and addresses for online website hosts. These servers will have mutual interaction with one another via private network protocols.

Domain Name System in computer networks gives you a service to translate the domain names into IP addresses because; a system does not understand any language apart from binary language i.e. 0 and 1. For example – example.com might translate to 198.105.232.4. It would be very tough for us to remember the IP addresses of each website which we want to visit. That is why DNS service is a must which converts the domain names into IP addresses.

All the servers are arranged in a Domain Name System hierarchy. At the highest peak of the chain lie the root-servers that contain the overall database of domain names existing on the internet and also their analogous IP addresses. The internet often integrates up to 13 root servers that have somehow become renowned for their unique roles in the system. These servers are maintained by multiple sovereign agencies and are fittingly labeled in alphabets beginning from A to M. Ten out of the 13 servers are inherent in the United States while the rest in London, UK, Japan, Stockholm and Sweden each.

As the DNS servers are distributed in a hierarchical scheme, only the top 13 has the content of domain names and the IP address in a database while the others that are employed at lower positions of the chain contain only specific bits of the entire database. The lowest levels of the servers are occupied by the Internet Service Providers (ISPs) or businesses. For instance, the Google remains multiple servers from various positions in the world that man the google.co.uk or google.com. Besides, the ISP also contains a fraction of the whole internet connection setup.

The Domain Name System networking frame goes according to the server or client’s architecture style. The web browser operates as a DNS client or also labeled as the DNS resolver and handle any issues delivered to the internet provider’s servers during the navigation between the internet websites. Should the server receive any requests which are not in its database, it will transform from the server to the DNS client. This is possible as the site may rarely be visited or situated geographically far.

Hence, DNS plays an important role in the Internet. DNS has to do the complete process several times but this process takes only milliseconds to get completed. There are many companies who are providing DNS network in the world. To know more on DNS, Web Hosting Geeks is a great site to get started.
