DNS Resolution
Domain: Internet & Web
🎯 Motivation
The process of looking up a domain name’s IP address via DNS. Happens every time you visit a website.
📋 Concrete Example
DNS resolution: type google.com -> DNS server: ‘google.com is 142.250.80.46’ -> browser connects to that IP. Takes 1-10ms. Cached for future visits. Happens behind the scenes.
🔗 Analogy
DNS resolution is like looking up a phone number in your contacts - you type Mom -> contacts app shows her number -> you call. DNS resolves domain names to IP addresses the same way.
