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.
