Instant DNS Propagation Checker
When you migrate a website or change email providers, you need to update your DNS (Domain Name System) records. Propagation can take time. Our DNS Lookup Tool queries global nameservers to see exactly what records are currently active for any domain.
DNS works on caching. It can take anywhere from 1 hour to 48 hours for changes to "propagate" worldwide depending on your TTL (Time To Live) settings.
A Canonical Name record maps one domain name (alias) to another. It's often used for subdomains like www pointing to the root domain.
