(CNN) - The Obama campaign has succeeded partly through astute, unprecedented use of the Internet. But some of the most obvious Web site domain names for the Obama-Biden ticket might not actually belong to the campaign anytime soon - if ever.
After hearing about Obama's selection for his number-two slot, anyone who tried to surf to obamabiden.org was re-directed to an eBay page selling that domain name for a starting bid of $100,000.
As of 6:30 p.m. ET, there were no bids listed.
The same seller lists 15 similar domain names up for sale, including obama-biden.com, obama-biden.org, and obamabiden-08.com.
Though the seller does not list his name on the ebay site, he does list it as public information at godaddy.com, where he purchased the site. That site shows that Luke Freudenberg bought the site back in December.
Freudenberg - whose city of residence is listed at both godaddy.com and eBay.com - did not immediately respond to a message sent via ebay or phone messages left on a work number. He does not have a home number publicly listed.
Perhaps the most obvious site for an Obama-Biden ticket, obamabiden.com, is owned by someone else.
Lyle Dean bought that site back in 2006. He also owns obamabiden2008.com.
On Friday, he told CNN's Abbi Tatton in an e-mail exchange that he has had no offers, but "numerous media inquiries."
Dean called himself an "enthusiastic supporter" of the Obama-Biden ticket.
