An online silent auction continued through noon Eastern time Monday. All unsold names, including hell.com, will next be placed on Moniker.com's Web site, where anyone can bid on them, Cahn said.

Moniker.com determines market values for the domain names through a process similar to real estate and property appraisals, using a wide range of factors including Web traffic, revenue and comparable sales, he said.

The company's next live auction for domain names is set for Jan. 17 in Las Vegas.
