A domain's expiration date and time can be calculated based on the expiration date in the WHOIS,[1] Auto-Renew Grace Period (0–45 days) and the Redemption Grace Period (RDP) of the registry managing the domain registration (30 days).
[2] According to the Generic Names Supporting Organization Council (GNSO)[3] Deletes Task Force Report (2003), a council organized under the Internet Corporation For Assigned Names and Numbers (ICANN), three specific modes of warehousing have been identified:[4] The Registrars Accreditation Agreement (RAA)[5] currently does not disallow this practice.
However, the ICANN community has open calls for policy changes to limit warehousing, as it is perceived as unfair to potential registrants.
[7] An additional concern is that companies pooling scores of drop registrars for additional registry connections will stand at the expiring domain spigot conducting domain tasting without paying, and then warehouse those that meet traffic criteria while denying the broader community a fair opportunity to compete for those expiring names.
ICANN has not yet amended the RAA with policies to limit domain warehousing and related practices.
