    Frequently Asked Questions

    What is NS propagation?

    NS (nameserver) propagation refers to the time it takes for DNS changes, particularly updates to your domain's nameservers, to spread across the global DNS network. When you change nameservers, it can take anywhere from a few hours to 48 hours for all DNS resolvers worldwide to recognize the new settings.

    Why check NS propagation?

    After changing nameservers (when moving a website to a new host, for example), you'll want to track the propagation progress to know when your domain will start directing traffic to the new servers. This helps you determine when the migration is complete and identify any potential issues.

    What affects propagation speed?

    Several factors influence propagation time, including the TTL (Time To Live) values set on your previous DNS records, the responsiveness of your old and new DNS providers, and the caching policies of various ISPs and DNS resolvers around the world.
