DEPARTMENT OF DEFENSE, SUPREME COURT, CONGRESS, US MILITARY, LAW ENFORCEMENT,
CIA, FBI, DHS, DEA, ATF, FEMA, NASA, EPA, NSA, US AIRFORCE, US ARMY, US NAVY,
NATO, CDC, CONTRACTORS, PENTAGON, US MARSHALLS, SAVVIS and others....
Our USG IP ranges blacklist is directed towards users and administrators who
wish to block unwanted communications with United States government networks,
intelligence agencies, military networks, and law enforcement agencies. It does
not include networks that host useful sites such as the Social Security
Administration, the US Postal Service, or your local unemployment office
website. This list is not intended to block non-threatening, government service
type websites that we all use. But it is designed to block the US Government
networks that you likely, really do not want traffic from your network reaching.
It is a simple CIDR formatted list, so you could use it for your firewall rules
just as easily as you could for a squid acl.
No other public source has published a more thorough list of US Government IP
ranges, undoubtedly there are many more undiscovered networks that are not yet
known and thus, not included in our list, However, it is the most complete list
of USG ranges publicly available, and we update it regularly.
---------This list is intended for legitimate network security uses
