government research legacy

A network of the US National Aeronautics and Space Administration (NASA), the federal civilian space agency.

What it's used for

  • Networking for NASA's research, mission, and administrative operations.

Notable

  • A US government / research network, not a commercial provider; it peers up to NASA's own AS270.

Interesting

  • Registered with ARIN in 1993, an early allocation reflecting NASA's long presence on the internet.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
