A method for identifying a registered domain name as auctionable is provided. The registered domain names may be pulled from a database of desired domain names, such as a collection of domain names that one or more interested entities have requested to register using a domain name registration system. Requesting a domain name may be probative of demand for the domain name. Accordingly a domain name receiving a threshold level of interest may be tagged as auctionable. For example a domain name may be tagged as auctionable when a total number of interested entities is at least equal to a minimum threshold of interested entities. Tagged domain names may be acquired by an escrow agent when a current registration expires and auctioned among interested entities. In addition, the owner of a tagged domain name may be notified to see whether the domain name can be auctioned before expiration.
