Understanding DNS Propagation

When you change DNS records (e.g., updating A records after a migration, adding MX records for new email, or setting TXT records for domain verification), changes don't appear instantly everywhere. DNS propagation is the time it takes for DNS servers worldwide to update their cached records. This typically takes 5 minutes to 48 hours depending on TTL values. This tool queries 3 major resolvers in parallel to show you the current state of propagation.
