Domain Name System

The Internet Domain Name System (DNS) is a critical component of the Internet infrastructure. The DNS associates user-friendly domain names (e.g., www.ntia.doc.gov) with the numeric network addresses (e.g., 170.110.225.155) required to deliver information on the Internet, making the Internet easier for the public to navigate.

NTIA is the Executive Branch expert on issues relating to the DNS and supports a multi-stakeholder approach to the coordination of the DNS to ensure the long-term viability of the Internet as a force for innovation and economic growth.

Supporting the President’s Call to Action Against Opioid Abuse

April 3, 2019

Fighting opioid abuse is a major priority of the Trump Administration. Nearly $6 billion in new funding over the past two years has gone into multiple programs to stop the flow of these dangerous drugs, and help those struggling with addiction. The President’s call to action resulted in the Justice Department’s shutting down the largest “darknet” for the online distribution of drugs in 2017.

We’re proud to announce a new step in the online battle against illegal opioid distribution. The Food and Drug Administration and NTIA have joined in a novel approach to work with domain name industry players to curb online availability and sales of illegal opioids.

As part of the effort, Neustar, the company that administers the .us top level domain on behalf of the Department of Commerce, announced it will step up enforcement of those who violate its existing ban on the sale or distribution of illegal opioids.
