In this article, we will try to explain the possible reasons behind this issue and some feasible solution that can be enforced to resolve this problem.
What is a DNS Server?
In the world of computer networking, every system is designated by a specified series of numbers called “IP Address”. These addresses are quite long and difficult to memorize for each system. Hence, in order to simplify the overall communication between systems and operator, networking engineers developed “DNS” (Domain Name System). The function of a DNS is to resolve domain names to numbers. To be specific, it resolves domain names into IP addresses. A DNS system basically works like a phonebook where the IP addresses of thousands of domains are stored alongside their unique IP addresses so that when a user enters a domain name, the DNS server will look for the domain name in the stored database and will automatically redirect you to the corresponding website via the IP address.

If we talk about the causes of this error, the culprit can be either the computer itself or the router, or the equipment on the provider side. Most of the time, the problem is caused by some misconfiguration on the ISP’s (Internet Service Provider) side. In such cases, there’s not much a user can do to resolve this problem rather than waiting for the ISP service to repair the issue on their own. But, in many cases, it has been observed that this problem may arise due to the presence of meager aberration on the user’s side. in such an event, there are are some proven solutions which can be applied to resolve the problem.
