What is DNS?

A common user does not have the knowledge of the fact that internet servers are not actually domain names but rather a combination of numerical digits comprising of a IP address. Many of us use the DNS without ever realizing the underlying complex structural hierarchy and the kind of computer prowess that goes into. It is a method or a framework of how computers exchange data on the internet and many other at personal and private level including the likes of TCP/IP protocol suite.


DNS is an abbreviation for Domain Name System, which is the established code that provides us with the essential supporting structure for web browsing. It provides computers, services or other resources with an infrastructure of them being connected either to a personal network or the wider world of Internet. The DNS system makes use or in a way converts the memorized domain names to IP addresses, which are specifically utilized for localizing and classifying related services or devices with underlying network protocols.

As computers and machines in general, are not familiar with the languages we use it is essential for them to have a sort of code or communication method in which they can express and exchange the various complexities and data among the computers as well as the growing population of mobile and portable devices. This is done by translating those into numerical addresses which is known as an IP address.For example, when you enter “” in your browser, part of the network connection includes resolving the domain name ”” into an IP address, like, for’s Web servers.

This is not limited to any specific process or task when using the internet but rather a common procedure used when computer needs to access something on the internet whether it be sending an e-mail or accessing any other website.

These IP addresses are basically the routes to our domains or websites that a particular user needs to access. All of this IP addresses and numerical codes need not be memorized or kept in mind all the mind as the DNS provides utmost convenience by making sure that all of the sites are accessible by only using the domain names of them. Sometimes the IP addresses keep changing with time to add more and more security features or multiple IP addresses are designated to a particular domain name just for convenience purposes. The DNS system basically has mapped all of our domain names onto specific IP addresses, the former being understandable to the common man and the latter being in the language that computers are familiar in. Whenever we connect to a local Wi-Fi, the modem assigns a network address to the device in addition, it also sends some crucial network settings to your computer that includes the DNS server which is then utilized in converting DNS names into their respective IP addresses.

DNS provides an efficient and effective way of grouping of root servers which consists of IP addresses corresponding to the name servers which are eventually registered in the Internet Domain. An excellent analogy can be made of DNS system with a Phonebook,The DNS system provides a similar function of keeping a directory of Domain names attributed to the more familiar terms in computing of IP addresses.

When a particular domain name is bought, the name registrar binds that particular domain name with at least two DNS name servers which are subsequently maintained and configured by the company that hosts the domain name. The DNS name server information is still kept safely in the root servers that make up the Domain Name System. The DNS name servers are kept in check by the hosting company so that they can take action in the future for that particular domain name with exact location on the exact web hosting server (determined from the IP address).

How to Configure DNS for Fastest Internet Speed?


After studying the above basics of a DNS servers and the kind of operations it performs staying mostly obscured to the average consumer it could be said that it does not directly influence the network or internet speed. Although, that is not totally true as it can have an effect on the time it takes to load a particular webpage onto your computer or mobile device.

As DNS servers are used to look up the different websites that the user wants to access, so any slow down or lagging behind in that computer could cause in creating an impression that your network connection is slow or the machine you are using is slow.

Changing the router’s DNS servers can aid in boosting the overall network speed. Many apps and websites offer this service of recommending you better DNS servers. After having those recommended server addresses, you should:

  • Visit your router’s page
  • Navigate to advanced settings
  • Note down your DNS server addresses for reference
  • Change them with your recommended DNS server addresses
  • Your device will then be upgraded with the new DNS server and should give you an instant speed boost

Free software for windows are also available that can dig deep right into the settings and produce better results for you. One of them is DNSjumper.Download the software from internet and is it is a portable application, extract it to a particular location. Drop-down menus are present that provide you with the best DNS servers as well as an automatic option of choosing the fastest by themselves and all your work is done.

As mentioned before DNS helps in several other functions and probably the most used would be email.

The reason all of these methods are incorporated are because of the face that the default DNS servers (provided by the network) are simply not that fast or they do timeout fairly quickly causing instability. Many of the third-party DNS servers are better equipped with safety and protection features that can help in avoiding phishing attacks. Third-party DNS servers also get rid of the nuisance of region-locked content and web inspections.
