📡 DNS Lookup Tool
Query DNS records for any domain. Check global propagation from 12 servers worldwide.
What are DNS Records?
DNS (Domain Name System) records are the instructions that live in authoritative DNS servers and provide information about a domain. They tell the internet how to handle requests for that domain — where to route emails, which servers host the website, and how to verify domain ownership.
Every time you visit a website, your device performs a DNS lookup to translate the human-readable domain name into the IP address that computers use to communicate. DNS records control this entire process.
What is DNS Propagation?
When you change DNS records, the new values don't instantly appear everywhere. DNS servers around the world cache records based on their TTL (Time To Live). Propagation is the process of these cached values being refreshed globally — it can take anywhere from minutes to 48 hours.
Our global propagation checker queries 12 major DNS resolvers across different regions so you can see if your changes have reached each location. If some servers show old values while others show new ones, propagation is still in progress.
