About this network

FFX-CNTY is registered to the Fairfax County Department of Information Technology — the IT organisation for Fairfax County, Virginia, one of the largest and wealthiest counties in the Washington, D.C. suburbs.

What it's used for

• Local-government networking: county offices, public services, schools-adjacent systems, libraries, and public safety infrastructure.

Notable

• Unusual in scale for a county: this is a large allocation, reflecting a local government that serves over a million residents and runs its own substantial IT operation.
• Registered with ARIN in 1994 — very early for a municipal or county government, and a reminder that Northern Virginia was wired into the internet before most of the country.
