and Technology (NIST), the federal measurement-standards agency.

What it's used for

  • Research and operational networking for a US government civilian agency.

Notable

  • A US government agency's network, not a commercial ISP or host.
  • The low AS number reflects an allocation from the internet's earliest years.

Interesting

  • NIST operates the nation's official time and frequency services, which many systems rely on for accurate clocks.
