What Is A DNS Server And How Is It Used For A Business

Updated: April 26, 2017

For those who do not know, a DNS server is a computer that is set up and registered to become part of the domain name system (DNS). The domain name system is the technology behind the public names of Internet domains and websites. They are the readable website addresses that we interact with on a daily basis. When a person searches with Google or another search engine, and the results are returned, cached under all of the descriptive text and links are the domain names of the websites that are listed. A DNS server is an element, and an essential component at that, of the overall process that makes it possible for sites to display in a web browser.

What Is a Domain Name System Server?

The DNS is a global network of primary and secondary servers maintaining a shared and distributed database that maps the name and IP address of all public accessed devices communicating with the Internet. This would be computers, tablets, smartphones, digital video recorders, and more. The secondary server functions as a backup to the primary server. A DNS server is typically through an Internet service provider or ISP. The servers find the IP address associated with a website and deliver that site to a web browser. In the address bar of the browser, the name of the site that is clicked is visible, but the IP address number that identifies that domain remains hidden in the background.

How Does a DNS Server Work?

These servers are the link between a browser and websites. They offer functionality for anyone in the organization that accesses the company network. This includes:
  • Content filtering – Implemented to make inappropriate sites and other unwanted content unavailable.
  • Malware blocking – This includes blocking sites that contain viruses, and harmful content.
  • Ad blocking – Perhaps the most annoying aspect of browsing the net are unwanted ads. Ad blocking does just what the name implies; it blocks those irritating ads from appearing in your web browser.

What a Domain Name Server Can Do for a Business

While using a third party Internet provider for DNS may be advisable for small businesses, more and more companies, even small business networks benefit from an in-house DNS. A local DNS is vital for enterprise level and larger companies. A DNS server keeps IP addresses inside a company network private. They are invisible to the outside world. It also helps to add zest to your network speeds. There are many ways to implement an in-house DNS. Much depends on the computer systems architecture that a business maintains. Once a DNS is installed and set up, it will typically do its job with the need for little human interaction. When correctly configured, the server reliably delivers hostnames and IP addresses on the network. It is wise to use the services of a firm that specializes in the implementation of servers, such as SourceTech, who can provide consultants for both setup and support. SourceTech recommends that mid-size to large companies implement a DNS. It is an essential tool for managing each IP device on a corporate network.
