Newborn Bennett Pankow joined his four older siblings in getting his own Internet moniker. In fact, before naming his child, Mark Pankow checked to make sure "BennettPankow.com" hadn't already been claimed. "One of the criteria was, if we liked the name, the domain had to be available," Pankow said. It was, and Pankow quickly grabbed Bennett's online identity. A small but growing number of parents are getting domain names for their young kids, long before they can do more than peck aimlessly at a keyboard. It's not known exactly how many, but the practice is no longer limited to parents in Web design or information technology. They worry that the name of choice might not be available by the time their babies become teens or adults, just as someone claimed the ".com" for Britney Spears' 11-month-old son before she could. The trend hints at the potential importance of domain names in establishing one's future digital identity.
