One day, recently, Google became a registrar and then we scratched our heads about the possibility that they would use it for advanced link mapping. But that was ruled down by an email sent t me by Nick Wilsdon from e3Internet that said Google can not use registrar data.
Eileen Rodriguez, a Google spokeswoman, hardly quelled the speculation by explaining that the whole thing was really a learning opportunity for the company. Google "has become a domain name registrar to learn more about the Internet's domain name system," she said recently in an e-mail message. "While we have no plans to register domains at this time, we believe this information can help us increase the quality of our search results."
