Summary

NASA (National Aeronautics and Space Administration)

United States · AI-generated

government research

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.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
