DNS delegation checker


Enter a domain above to check. This page can be used to check that delegation information for a domain is up to date and correct at the registry. A few other checks are done on the usabilility of the domain, such as whether MX records for the domain are set up correctly.

Note that only UDP DNS queries are done; the script makes no attempt to check if WWW or mail services are operational, nor does it check DNS entries apart from those associated with the delegation and common services.
