Whois refers to a system that allows you to search more information of registered domain names. Generally speaking, when you register a new domain, you are required to provide specific contact information based on The Internet Corporation for Assigned Names and Numbers, data is afterwards stored in the Whois database.

OpenWhois is a desktop tool of the service that enables you to quickly perform queries about various domains in real time.

Considering that it is based on the service with the same name, it does not come as a surprise that the interface is basically the same. You can get started by typing or pasting the name of the domain in the dedicated section. According to the developer, some of the perks of the tool include support for hundreds of history and index queries, multiple key fields and suffixes.

The application provides the required information in real time along with the information you can typically find with the service. More precisely, after you input the domain, you can learn more about the category, registrant name and organization, creation and expiration date, update time, domain ID, so on and so forth.

In case you hit multiple results for a specific query, then you can consider using the Advanced Options to narrow down your search. Consequently, you can include filters such as type, GTLD, category, state, hyphens, pure letter or number.

If you are using the Whois service to look down domains but would prefer not to use your browser for this, then OpenWhois provides an alternative in this sense. The service has been known to maintain an accurate record of the domains over the years and hence, it can reduce the chances of unauthorized modifications or transfers to domain names.
