Description

The internet works on IP addresses, but humans prefer easy-to-remember names like telusko.com. So how does the internet translate domain names into IP addresses? In this video, we explore the Domain Name System (DNS) — the system that acts like the phonebook of the internet. We’ll understand how DNS works step-by-step, including the role of root servers, TLD servers, and authoritative name servers.
