I originally made domain propagation tool while migrating all my sites from various hosting companies to a single hosting platform and have now decided to make it available to anybody who would like to use it.

About Us

Whenever a web site is moved from one server to another or from one hosting company to another, its IP address may change and DNS servers around the world will be updated with its new IP address. This process can sometimes take several days as the new IP address information is passed from DNS server to DNS server.
