Your Data Center - Full DNS Zone Check

Your Data Center's DNS Zone Check performs several tests on your zone (ie:domain) to ensure that it is correctly
configured and can be safely delegated, providing a certain quality to your domain (see the benefit section).

For detailed information on how to fill this form see the help section.

The time required to completely verify a zone can take from 10 seconds up to 5 minutes depending on the network speed of the server being accessed.
If execution takes more than a minute it generally means slow access to your nameservers (configuration error, firewall, ...) is occurring. Expect a timeout.

Benefit

Among the tests performed you can find checking for:

authoritative nameserver for your zone, ensuring you will be able to use your domain from outside your network.
correct list of secondary nameservers, so that if your primary nameserver is temporarily unreachable, you will still be visible on the internet;
check for mail delivery, so that you don't become the prey of spammers and become blacklisted
