How DNS Caching Speeds Up Your Web Browsing

We dive into the often-overlooked hero of internet performance: DNS caching. While most people focus on fiber optic cables or server hardware, the Domain Name System acts as the internet’s phonebook, translating human-readable domain names into IP addresses. In this episode, we explore how recursive resolvers like Google Public DNS and Cloudflare work to minimize latency through intelligent caching strategies. We break down TTL values, the difference between local and global caches, and why your browser’s cache matters just as much as your ISP’s. If you have ever wondered why some websites load instantly while others stutter, the answer often lies in how efficiently your device is storing and retrieving these critical mapping records. We also look at recent shifts in privacy laws affecting DNS logging and what that means for your digital footprint.
