Kupietzky's Oversee.net is one of a number of companies that brokers the resale of such domain names. While registrars such as Network Solutions offer the ability for anyone to own a previously unclaimed Internet domain name, usually for less than $20, a secondary market of already claimed but seemingly valuable domain names has long existed.

"It's a phenomenal domain name. When you have a one word domain name like this, it has multiple meanings," and thereby could be used in any one of a number of different industries, noted Jason Miner, senior vice president of sales and business development for NameMedia, which operates a domain name marketplace.

Miner estimates that Sun.com could sell for $1 million, if not more. Such a sale would not be unprecedented. In 2010, Zip.com sold for over $1 million, Dating.com sold for $1.75 million and T-Shirts.com garnered $1.26 million.

Of course, any of these scenarios would depend on Oracle re-registering the domain name, which, on latest check, expires on March 20, 2012. If Oracle forgets to do so for some reason, then anyone could pick it up for around $10. Now that would be a wise acquisition.
