Summary
Federal Aviation Administration (FAA)
government legacy
FAA is the autonomous system of the United States Federal Aviation
Administration, the agency of the Department of Transportation that regulates
civil aviation and runs the national air traffic control system.
What it's used for
- Agency networking: FAA facilities, administrative systems, and the agency's internet-facing services.
- The address space is government institutional space, serving FAA staff, sites, and systems rather than any commercial customer base.
Notable
- The FAA holds a full legacy
/16(155.178.0.0/16) announced from this ASN, a size handed out in the era when federal agencies took direct allocations. - The ARIN autnum registration dates to 1994, consistent with an agency that was connected in the internet's early institutional phase.
Interesting
- Safety-critical air traffic systems run on dedicated operational networks rather than the public internet, so a government ASN like this reflects the agency's enterprise and public-facing IT, not the radar and comms backbone itself.
