We start verifying if you have changed your DNS settings within few minutes after you add the domain to the system and keep checking at regular interval for few days. If for some reason you are changing the DNS server on your domains, your domain will be removed from our system and you should add it again if needed.

There is also another option for making the host active on our DNS server before changing the DNS. You can simply verify the ownership of the domain by clicking on a link sent to the administrator email address on Whois.
