About this network

A network of the National Oceanic and Atmospheric Administration (NOAA), the U.S. civilian agency responsible for weather, climate, oceans, and fisheries. The handle NOAA-SILVERSPRING points at NOAA's headquarters campus in Silver Spring, Maryland.

What it's used for

• A single /24, plus an IPv6 prefix, serving NOAA systems. Administrative contact for the AS is NOAA's N-Wave, the agency's enterprise network, run out of Boulder, Colorado.

Notable

• This is government research address space. Traffic from it is agency staff and agency systems: weather and ocean data, modelling, and the services NOAA publishes from them.
• NOAA operates several networks. This one is a small, specific block tied to the Silver Spring headquarters, not the whole of the agency's address footprint.

Interesting

• The ASN is a genuine mid-1990s ARIN allocation, part of a sequential run issued in June 1995. The organisation handle's -Z suffix is an artifact of ARIN's legacy record cleanup, not a sign that the number changed hands.
