The above WHOIS results have been redacted to remove potential personal data. The full WHOIS output may be available to individuals and organisations with a legitimate interest in accessing this data not outweighed by the fundamental privacy rights of the data subject.

.CO Internet, S.A.S., the Administrator for .CO, has collected this information for the WHOIS database through Accredited Registrars. This information is provided to you for informational purposes only and is designed to assist persons in determining contents of a domain name registration record in the .CO Internet registry database. .CO Internet makes this information available to you "as is" and does not guarantee its accuracy.

By submitting a WHOIS query, you agree that you will use this data only for lawful purposes and that, under no circumstances will you use this data:  (1) to allow, enable, or otherwise support the transmission of mass unsolicited, commercial advertising or solicitations via direct mail, electronic mail, or by telephone; (2) in contravention of any applicable data and privacy protection laws; or (3) to enable high volume, automated,  electronic processes that apply to the registry (or its systems). Compilation, repackaging, dissemination, or other use of the WHOIS database in its entirety, or of a substantial portion thereof, is not allowed without .CO Internet's prior written permission. .CO Internet reserves the right to modify or change these conditions at any time without prior or subsequent notification of any kind. By executing this query, in any manner whatsoever, you agree to abide by these terms.  In some limited cases, domains that might appear as available in whois might not actually be available as they could be already registered and the whois not yet updated and/or they could be part of the Restricted list. In this cases, performing a check through your Registrar's (EPP check) will give you the actual status of the domain. Additionally, domains currently or previously used as extensions in 3rd level domains will not be available for registration in the 2nd level. For example, org.co, mil.co, edu.co, com.co, net.co, nom.co, arts.co, firm.co, info.co, int.co, web.co, rec.co, co.co.

NOTE: FAILURE TO LOCATE A RECORD IN THE WHOIS DATABASE IS NOT INDICATIVE OF THE AVAILABILITY OF A DOMAIN NAME. All domain names are subject to certain additional domain name registration rules. For details, please visit our site at www.cointernet.co .
