DNS Propagation Checker
DNS Propagation Checker lets you check your Domain/IP Address against a selected list of DNS servers in every corner of the world. This tool can be used to check if the propagation has completed after perfoming changes to the DNS configurations.
What is DNS propagation?
DNS propagation is the period of time used to check the current status of DNS globally. Any changes you make to the DNS of a hostname may take up to 48-72 hours or more. Here is why DNS Propagation Checker is important.
Why is DNS not propagating?
The ISPs across the world have a different caching level. The DNS client or the server may cache the information the DNS records in its DNS cache. That information is temporarily cached, and DNS servers will go for the updated DNS information when TTL (Time to Live) expires.
How do you speed up DNS propagation?
This can be achieved by simply lowering the TTL (Time to Live) to the lowest possible value. So any changes you apply to an old record will take into effect quicker because the TTL will expire quickly.
What happens in case you time an invalid hostname (or not exist domain name)?
The DNS servers will return an error name. This is known as NXDomain response (for non-existent domain).
