#dns #domain_name_system #dns_lookup • Understanding the DNS, Domain Name System, and how it works is an important part of any web developer's journey. The DNS lookup process is how domain names, contained in a URL, are resolved into IP addresses and received by the user's browser to make the actual HTTP request to the server to get the sought-after resource. • The DNS lookup process is also important for software developers and engineers interested in security. DNS poisoning is one of the big threats on the web and understanding how the Domain Name System works helps a lot in taking precautions and security measures. • In this video, I explain what is DNS and how it works by starting with an analogy that illustrates the problem DNS solves. Then we dive deeper into the details of the Domain Name System, the different DNS servers; that is to say, DNS resolvers, DNS Root Servers, DNS TLD servers, and Authoritative Servers. I explain the difference between them and through a typical scenario, I illustrate how the process of the DNS lookup takes place.
