About this network

AS297 is an operational network of NASA, the US federal civilian space agency. It carries NASA's own institutional and mission-support traffic rather than any commercial service.

What it's used for

• Internal and mission-support connectivity for NASA facilities, programs, and science operations.

Notable

• An IP here is a US government / federal-agency address, not a consumer ISP, mobile carrier, or hosting provider.
• NASA runs several ASNs across its centers and programs; AS297 is one of the long-standing ones, allocated in 1989 and registered through ARIN.

Interesting

• Its low AS number reflects an allocation from the early days of the internet, when NASA networks predated most of today's commercial providers.
