Temporary Failure in Name Resolution

If you have recently installed Kali Linux Ubuntu or any other LINUX operating system variant you have probably faced or maybe you are facing the issue of “temporary failure in name resolution”. In this article, we will share a permanent simple, and straight solution to this problem. The latest Linux OS versions are coming with an error where the end-users having been connected to their Wifi aren’t able to surf the internet or even the ping command also through the same error message. Let’s know a little bit about what this error is and why you are facing this issue.

Name Resolution in Linux

        You can relate this with a real-life example: suppose a guy named Mike gets a pizza delivery job in another city, he doesn’t know the exact addresses of the pizza company’s permanent customers, so the sales manager gives him an address book that contains numbers and addresses of all their customers, by which he can now deliver the pizza easily and quickly.

        The same thing applies here: the internet is nothing but a large network of interconnected computers and those computers have their addresses called IP addresses. Computers communicate through IP addresses and because humans are not very capable of memorizing large numbers, instead they assign the names to those IP addresses to remember them easily. So the example of Mike illustrates the scenario of communication and transfer of physical entities, similarly, the online devices use DNS (Domain Name System) as an address book or phone book.

        In DNS the conversion process of domain names to IP addresses and IP addresses to domain names is called Name Resolution. In simple, name resolution is the main actor who resolves our domain name-related queries and provides us with the required IP addresses.
