AS10343 — AS10343 - National Aeronautics and Space Administration

AS10343 announces 5 IPv4 prefixes covering 123,904 addresses and 2 IPv6 prefixes.

About this network

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.
