DNS Propagation Checker
Check if your domain is pointing to Web60 and whether DNS has propagated.
What is DNS Propagation?
DNS (Domain Name System) is the internet's phonebook. When someone types your domain into a browser, DNS servers translate that name into the IP address of your web server. When you change your DNS records — for example, pointing your domain to a new host — those changes need to spread across DNS servers worldwide. This process is called DNS propagation.
How DNS Resolution Works
Your browser asks a DNS resolver for the IP address behind your domain. The resolver checks its cache first, then queries authoritative nameservers if needed. This lookup typically takes 20-100 milliseconds.
Why Does Propagation Take Time?
DNS records are cached at multiple levels — your ISP, your browser, and intermediate resolvers. Each cache respects the TTL (Time To Live) value set on the record. Until every cache expires, different users may see different results. Full propagation typically takes 15 minutes to 48 hours.
What is an A Record?
An A record (Address record) maps your domain name to an IPv4 address. It's the most fundamental DNS record type — it tells the internet which server hosts your website. When you move your site to a new host, updating the A record is the primary step to complete the migration.
Other common record types include CNAME (alias to another domain), MX (mail server), and TXT (verification and security policies like SPF).
Tips for Faster DNS Propagation
Lower your TTL before making changes
Set the TTL to 300 seconds (5 minutes) at least 24 hours before you update your DNS. This ensures caches expire quickly once the new record is live.
Double-check the IP address
A typo in the A record is the most common DNS mistake. Verify the exact IP with your hosting provider before saving.
Clear your local DNS cache
After making DNS changes, flush your local cache (ipconfig /flushdns on Windows, sudo dscacheutil -flushcache on macOS) to see results immediately on your own machine.
