Root nameserver check

September 10, 2003 by davidc

This form queries all the nameservers for the root you've specified to find out what their records show for the NS of the domain in question. This is useful if you have submitted nameserver changes and you don't know whether they are yet in any or all roots. It returns a list of what each root (gtld, cctld etc) nameserver is serving as NS records. Repetitive, automated or abusive use of this page is strictly prohibited. If you want to run this yourself, download the source.

Updated 17/04/2009 to use "host -v" and check for all NS records including non-authoratitive ones (e.g. if you're checking a .co.uk domain that has .com nameservers).
