"I'd want to research and try to figure out how easy it is to find out what school she goes to and where she lives" based on the Web site and domain name, Pankow said.

GoDaddy and many other registration companies offer proxy services that let domain name buyers register anonymously. Otherwise, the person's name, address and other contact information are publicly searchable.

Notwithstanding the privacy concerns, Adelman said domain names for kids have become more and more popular as parents start to get domains for their business or family and realize how difficult it is to find ".com" names not yet claimed.

But the numbers are still relatively low. Our Baby Homepage, which lets parents set up personal baby pages with photos and greetings, says only 10 percent of its customers have bought their own domains. A similar service, Baby's First Site, considered selling domains for parents but didn't get much interest.

Brian Vannoy, founder of TotSites, said parents might need more lessons on safety measures such as how to password-protect sites. But he believes the hurdles can be overcome once parents who are less-savvy about technology see the benefits.

"It's easy to remember," Vannoy said. "Everybody knows the new baby's name."
