Internet names for Asia launched

The .asia regional internet domain has officially opened for business, with big firms expected to grab addresses.

Governments and companies can now register interest in specific domain names, such as www.namehere.asia.

Companies will be able to register domains for which they own a trademark and governments will get a chance to earmark those on a reserved list.

The general public will get a chance to snap up their own .asia domain when the landrush starts in February 2008.
