With the ever-increasing use of the internet and sophisticated digital technologies, network problems have increased manifold. One such problem seems to be the DNS server.

DNS stands for Domain Name System. The role of a DNS server is to translate the name of the domain you want to visit into the IP addresses that match that domain name.

For instance, your home network depends on a DNS server provided to you by your internet service provider. If you change the DNS server on your router, all the devices in your network will be able to use it. When your browser sends the server any domain name, the server runs a complex interaction with many other servers to provide you the corresponding verified IP addresses. In case the domain is something you use frequently, the DNS stores the information in its cache files for easy access.

As you can see that your DNS server is highly important for all your internet activities, any problem within your system can have a drastic effect on it. However, an essential thing to note here is it is pretty tricky to change the DNS settings but very beneficial.

By switching the DNS server on your router, you can configure parental control settings on the OpenDNS site, restrict multiple types of internet websites, and monitor those which you have viewed via your home network.
