What Is Whois Checker

When registering a domain name, the Internet Corporation for Assigned Names and Numbers (ICANN) requires that your domain name registrar send your personal contact information to the WHOIS database. Once your listing appears in this online domain WHOIS directory, it is publicly available to anyone who chooses to verify domain names using the WHOIS search tool.

There is a variety of third parties that can verify domain names in the WHOIS check database, including:

Individuals check domain names for expiration dates

Registrars check domain names when transferring property

Authorities control domain names when investigating criminal activities

As an accredited domain name registrar, Network Solutions® must comply with the requirements of a WHOIS database established by ICANN. However, to ensure that customers are comfortable with the visibility of their personal information, Network Solutions offers three options for its list of WHOIS databases.

CO Internet, S.A.S., the administrator of the.CO Domains has received this information from the Whois database through the Accredited Registrars. This information is only a guide provided to determine the content of the registrations of a domain name in the Internet Registry database. This information is presented according to the available information, and its accuracy is not guaranteed.

By submitting a WHOIS query, you agree to use this information only for legal purposes and that under no circumstances will you use this information to:

(1) Allow, enable or in any way assist in the transmission of mass advertising, commercial and unsolicited via email, mail or telephone

(2) In violation of any applicable law for data protection and privacy

(3) To allow automated or high volume electronic processes using the Registry or its systems. The collection, appropriation, dissemination or any other use of the WHOIS database in its entirety or any substantial part thereof, is not permitted without the express written authorization of CO Internet. CO Internet reserves the right to modify or change these conditions at any time and without notice. By executing this query in any way, you agree to abide by these terms.


In limited circumstances, domains that appear available in the whois may not be available because they may have been previously assigned and have not been reflected in the whois database or may not be available to be registered because they are part of the database. In these cases, a review from your Registrar (EPP Check) will give you the current status of the domain. Also, domains used as extensions in third level registries currently or previously will not be available to be registered in the second level. For example:,,,,,, arts.Co, firm.Co,,,,, All domains are subject to additional registration and processing rules.
