Here's what that means. The U.S. government is giving up control over the Internet Corporation for Assigned Names and Numbers (ICANN). ICANN is the body that coordinates unique names for websites, making it responsible for the closest thing there is to fixed locations on the internet. For years, ICANN has contracted that function out to the Department of Commerce's National Telecommunications and Information Administration. It's a wordy jumble for a vital function: Without the locations, browsers can't find sites. And a site that can't be found is a site that, for all intents and purposes, doesn't exist on the internet.
