.gov puts U.S. governments on the internet.

Bona fide government services should be easy to identify on the internet. The DotGov Program, part of the Cybersecurity and Infrastructure Security Agency, operates the .gov top-level domain (TLD) and makes it available to U.S.-based government organizations, from federal agencies to local municipalities. Using a .gov domain shows you’re official.

We make it easy to register a .gov domain name and ensure that the name resolves in the global domain name system (DNS). DNS maps easy-to-remember names on top of hard-to-recall numbers, allowing you to use instead of something like

.gov domains are intertwined with access to government services, and that makes .gov critical infrastructure for governments, citizens, and international internet users. We work to make .gov a trusted, secure space: we publish our policies, recommend security best practices, and make .gov domain data publicly available.

We put U.S. governments on the internet, but there are some things we don’t do. DotGov doesn’t offer authoritative DNS services, host .gov websites or email, or monitor all .gov network traffic.

If you’re from the government, we’re here to help. Contact us at
