You probably surf the web<\/strong> all the time and have a basic idea of how things work in the world of the internet but what you don\u2019t know are the intricate details that make it all work. In this article, you will learn all about how a DNS works<\/strong> and what to do when you need to change it.\u00a0<\/span>\u00a0<\/span><\/p>\n

Whenever you search for something on the internet<\/strong> or open a certain website<\/strong>, you type in the webpage address and within minutes you have it there on your screen. But how the internet accesses that particular webpage<\/strong> is something very interesting that has a lot of logical mechanisms going on behind it. <\/span>\u00a0<\/span><\/p>\n

How Does a Web Request Work?\u00a0<\/strong><\/p>\n

Let us assume that you want to access the <\/span>ProPakistani<\/span> webpage from your browser. You type <\/span>www.propakistani.pk<\/span><\/a> in the search bar of your web browser. Your browser<\/strong> then sends a request to the web host of that page which then opens up the webpage you are trying to reach. But that\u2019s not all that is to it. There is a major key player involved in the whole process. <\/span><\/p>\n

The internet servers that are responsible for routing your requests do not understand domain languages<\/strong> like <\/span>www.propakistani.pk<\/span><\/a> but instead, they respond only to numeric values and IP addresses such as 24.465.085.096. The request generated by the router is received by the DNS<\/strong> which then translates it into the respective IP address<\/strong> of the webpage you are trying to load. <\/span><\/p>\n

Upon receiving the IP address, the computer generates a connection with it and continues to load the page. What\u2019s amazing about this whole process is that it takes less than a second to process. Some DNS requests<\/strong> take even half the time and do the job in 40 milliseconds!\u00a0<\/span>\u00a0<\/span><\/p>\n

\"HowWhat is a DNS and What Does it Do?<\/span>\u00a0<\/span><\/h2>\n

The term DNS stands for Domain Name System<\/strong>. In simpler words, it is a language used by computers to communicate with each other. All the devices in the world are assigned a particular IP address. DNS serves as a phone directory<\/strong> that associates each IP address with its domain name.\u00a0<\/span>\u00a0<\/span><\/p>\n

Why Would You Want to Change Your DNS?<\/span>\u00a0<\/span><\/h3>\n

You might want to change your DNS because of different reasons. Here are some:<\/span>\u00a0<\/span><\/p>\n

    \n
  1. To access a webpage<\/strong> that is restricted in your geographical area.\u00a0<\/span>\u00a0<\/span><\/li>\n
  2. To boost the speed of your internet connection.\u00a0<\/span>\u00a0<\/span><\/li>\n
  3. To maintain a web browsing experience<\/strong> for children that is safe and full of parental controls.\u00a0<\/span>\u00a0<\/span><\/li>\n
  4. To protect your devices by allowing third-party DNS<\/strong> servers to provide more security features.<\/span>\u00a0<\/span><\/li>\n
  5. To remove any glitches in the performance of your internet connection that might be linked with the DNS<\/strong> (such as slow connection etc).<\/span>\u00a0<\/span><\/li>\n<\/ol>\n

    VPN vs DNS<\/span>\u00a0<\/span><\/h3>\n

    Sometimes, a certain webpage is blocked or restricted<\/strong> due to geographical limitations and bans. Most of the time using a VPN changes<\/strong> your IP address and it cannot be linked back to the location that you\u2019re trying to access the webpage from.\u00a0<\/span>\u00a0<\/span><\/p>\n

    In a similar fashion, changing your DNS masks your location and you can access the webpage. The only difference is that by using a VPN,<\/strong> your connection gets rerouted while the DNS shows that you are in a different location<\/strong> to the server. Since a VPN offers more privacy, it also tends to slow down your internet connection resulting in a delayed response from the webpage. <\/span>\u00a0<\/span><\/p>\n
