Summary

government space research science

AS10343 belongs to the National Aeronautics and Space Administration, the United States civil space agency. It is one of several NASA-held ASNs and carries agency network space rather than any commercial service.

What it's used for

  • Federal agency networking: NASA centre and facility connectivity, research and mission-support systems, and the agency's own administrative infrastructure.
  • The space here is legacy federal allocation (a 129.99.0.0/16 class-B plus a 198.9.0.0/17 block and its more-specifics), the shape of an organisation that received addresses early and has kept them.

Notable

  • Government, not carrier or hosting. RIS sees 5 IPv4 prefixes / 123,904 addresses announced against only 2 observed BGP neighbours. That ratio is the decisive evidence: a wholesale transit network with six figures of address space would peer with hundreds of ASes. Two upstreams and a large, contiguous, early-allocated block is the classic single-tenant federal or enterprise network — it buys connectivity, it does not sell it.
  • The announced set is a handful of aggregates deaggregated into /17, /18 and /19 pieces, consistent with traffic-engineering across a small number of transit links rather than a customer cone.

Interesting

  • NASA is unusual among federal agencies for how much of its address space is visible in the public routing table at all: much agency networking is closed, but NASA's science and research mission means a substantial part of the organisation is reachable from the open internet.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
