Domain Name System (DNS)
The system that translates human-readable domain names into IP addresses.
Quick Definition
The system that translates human-readable domain names into IP addresses.
Full Explanation
The Domain Name System (DNS) is the internet's phone book, translating human-readable domain names (like makewebsite.fast) into IP addresses that computers use to communicate. DNS lookup is the first step in loading any webpage and can add 20-200ms to load time depending on the DNS provider and caching. Fast DNS providers like Cloudflare (1.1.1.1) and Google (8.8.8.8) can reduce lookup times. DNS propagation refers to the time it takes for DNS changes to spread across the internet. Using DNS prefetching (rel='dns-prefetch') can help reduce DNS lookup time for third-party resources.
