How DNS Works
What happens between typing a site name and your browser finding it
What you'll learn
- What DNS does
- The lookup path: cache, resolver, root, TLD, authoritative
- TTLs and caching at every step
- Why DNS changes take time to show up
In this video, we'll look at what happens when you type a website address into your browser, and how DNS (Domain Name System) turns that name into an IP address. We'll cover DNS resolvers, root servers, TLD servers, authoritative name servers, and how they work together to find the right address.
We'll also look at DNS caching, TTL (Time to Live), and why DNS changes can take time to show up everywhere.
