DNS for System Design Everthing You Need to Know

What actually happens when you type a URL into your browser? In this video, we break down the Domain Name System (DNS), often called the "phonebook of the internet." Understanding DNS is critical for any System Design Interview (especially for FAANG/MAANG companies) because it is the first point of entry for any scalable system. We cover the entire lifecycle of a DNS query, the difference between Iterative vs. Recursive lookups, and how to use concepts like TTL (Time to Live) and Geo-Routing to optimize latency in distributed systems. Key Concepts Covered: A Records vs. CNAME Records Recursive Resolvers vs. Root Servers Routing Strategies (Weighted, Latency-based, Geo-location) 🚀 Welcome to SystemSage!
