Exchange of Letters - U.S. Government Administered TLDs
NTIA exchanged letters with ICANN in June 2016 reaffirming the U.S. Government’s administrative authority over the .mil, .gov, .us, and .edu top level domains.
The .gov means it’s official.
Federal government websites often end in .gov or .mil. Before sharing sensitive information, make sure you’re on a federal government site.
The site is secure.
The https:// ensures that you are connecting to the official website and that any information you provide is encrypted and transmitted securely.
