Yes GoDaddy is for sale in an auction, and experts expect to sell at least $1B.

"Based in Scottsdale, Ariz., GoDaddy.com is owned by Bob Parsons, who founded the company in 1997 and is its chief executive—a man the company website describes as "not shy to speak his mind." The company is well known for its edgy advertising, including Super Bowl commercials and ads featuring different "Go Daddy Girls," including racing car driver Danica Patrick.

In addition to registering domain names, GoDaddy.com sells e-commerce, security and other services to people and businesses looking to manage their online presence. The company posted revenue between $750 million and $800 million in 2009, according to people familiar with the matter.

Two smaller competitors, Register.com and Network Solutions, have both been in private-equity's hands. Earlier this year, technology-focused buyout firm Vector Capital sold Register.com to another web registration and design provider , Web.com Inc., for $135 million. Network Solutions is owned by General Atlantic Partners." (Online WSJ, 2010)

I personally own hundred of domain names from GoDaddy that I bought though the after market. The domain name business operations is smooth and easy to complete your transaction. Not only domain names, GoDaddy provide hosting, domain auction, resellers, e-commerce, copyrights, SSL, and other related services that you can use for your online business. I am also a GoDaddy reseller (www.Moscom.com) which I use to provide domain name and hosting service to my direct customers.

I hope the domain name business operations will not change and will continue the sweet ride of success.
