If you are experiencing a slow internet connection or you are unable to access some websites there must be something wrong with your default DNS server. The only immediate solution is to change DNS Server on your PC or mobile device. Changing the DNS server and setting a private DNS not only keeps you safe from a malicious website but also speeds things up. But before moving on to how to change the DNS server on Android, iOS, Mac, and Windows, knowing about DNS is very important. Let’s get started.


What is DNS?

DNS or Domain Naming System is nothing but a dictionary of IP address to Domain Name Server. With every DNS there is an IP address associated with it. In simpler words, DNS is the human-readable format that machines cannot understand whereas IP address is machine-readable. You can access any website by its domain name or by IP address like Facebook can be accessed using the 157.240.10.35 IP address.

These IP addresses are just numbers used by computers on the internet to communicate with each other. Humans cannot remember numbers and it becomes very inconvenient to use IP addresses while using the internet. So to make things easier for us, DNS came into existence. Now all you have to do is enter the domain name and you will be at the desired place.

Now that you know what is DNS everything might look simple but it is actually not that easy. There are three types of DNS servers namelyDNS stub resolver server, DNS recursive resolver server, DNS authoritative server.


What Happens When you Change the DNS?

In simple words change the DNS server means gaining control over the network to navigate the internet. When you will be changing the DNS server, you will have to set the IP address by which you will be instructing the browsers or any other web applications to use the new DNS server to complete your command.

The reasons you might want to change DNS Server on any device whether it is Android, iPhone, or Windows PC:

  • The default servers are sometimes slow in comparison to third-party DNS servers. So, if you want to speed things up you can change the DNS server on your device.

  • Secondly, some DNS servers provide better services such as blocking bad content and keeping you safe from prying eyes.

  • Additionally, you can have access to blocked content when you change the DNS servers on Android, iOS, Mac, and Windows PC.
