No. Currently, access to the .CO Zone File is not available to the general public. .CO Accredited Registrars and Affiliate Partners may apply and be granted access to the .CO Zone File based upon signing a Zone File Sharing Agreement and paying a one-time fee. Access is granted on a case-by-case basis. Interested parties should contact [email protected] for more information.
