The meeting in Paris will consider whether to throw open the current limited pool of top-level domain names, such as .gov and .fr, to any combination of letters and numbers which any organisation may register (within certain guidelines).
The changes could herald in a new generation of names such as Coca-Cola buying .coke, and of course the sex industry scrambling for .sex.
Icann said that registering a top-level domain would cost between $100,000 and $500,000. Applications would be accepted from around April 2009 and the first new sites would go live later in the year.
