The .com suffix generally implies an American domicile, though not exclusively. (The U.S. also has a .us suffix, but it is rarely used.) Canny opportunists are registering site names like Amazon.com.nl in the Netherlands or Infoseek.com.id in Indonesia, anticipating that Jeff Bezos or Disney will pay big bucks for the names as they move ahead with international e-commerce plans.
And while the .com suffix has overwhelmingly captured the market's imagination, accounting for about 90% of all registrations, there are plenty of e-commerce opportunities in the less fashionable .net and .org.
