Episode 59: DNS Basics — Name Resolution and Record Types
DNS, or the Domain Name System, is the internet’s phonebook, translating human-friendly names into machine-friendly IP addresses. In this episode, we explain how DNS works, including recursive queries, authoritative servers, and the resolution chain that begins with the root servers. You’ll learn what happens when you type a web address into your browser and how DNS finds the correct IP behind the scenes.
We also cover essential DNS record types such as A, AAAA, MX, CNAME, NS, and PTR. Each record type has a specific role in name resolution and service discovery, and understanding their function is key for both troubleshooting and configuring DNS zones. Whether you’re resolving slow loading websites or configuring internal domains, this episode gives you the foundational knowledge to understand and control name resolution.
