Whois search

With the whois search you can quickly identify all the domains owned by an entity. The Whois information is available publicly, but Profundis is the first service which allows you to instantaneously search it using wildcards on multiple fields.

How to use it?

You can try the WHOIS sample query. For most people, one of the most interesting fields will probably be registrant_organization, e.g. registrant_organization:"*some company name*".

As with all Profundis datasets (DNS, hosts, etc) you can combine the search fields as below.

registrant_organization:"*some company name*" AND nameservers:"*.something.com"
