The US House of Representatives has approved a plan to create a kid-friendly Internet zone free of violence, pornography and other adult material.
Under the scheme an area within the United States's ".us" internet domain would be set aside for websites deemed appropriate for children 12 years old and younger.
The sites would have a ".kids.us" address and not contain sexually explicit material, hate-speech, violence or other material deemed unsuitable for minors.
The bill's sponsor, John Shimkus, an Illinois Republican, claims that the move will tame the Wild West of the World Wide Web.
The bill, which has the backing of opposition parties, would regulate content only on a corner of the internet that falls directly under US government control, and stays within the "free speech" laws of the United States.
It is the latest attempt to keep children away from sexually explicit material after the US Supreme Court threw out the 1996 Communications Decency Act, as an infringement on free speech, and sidelined the 1998 Child Online Protection Act.
More recently, lawmakers had hoped the international body that controls domain-name policy would set up a ".kids" domain.
The ".kids.us" subdomain would be policed by NeuStar, the Washington-based telecommunications company that won the contract to manage the ".us" country-code domain last year.
Websites in the domain would be prohibited from linking to sites outside it, and would be forbidden from having chat rooms.
