About this network

JAXAnet is the network of the Japan Aerospace Exploration Agency (JAXA), the national space agency of Japan, run by its Information Systems Department.

What it's used for

• Networking for Japan's national space program: agency campuses and research centers, engineering and mission-support systems, and the movement of scientific and satellite data.
• A government research network serving the agency's own facilities, not a commercial ISP or host.

Notable

• A national space agency is an unusual kind of holder to find this low in the AS number space, and it is one of the few non-US organizations down here — the low numbers are dominated by American universities, federal agencies, and early corporate adopters.
• Registry records associate the ASN with JAXA's Tsukuba networking, matching the agency's Tsukuba Space Center, its principal center for spacecraft development and operations.

Interesting

• JAXA was formed in 2003 from the merger of Japan's three predecessor space organizations, so the agency as it exists today is younger than the AS number it uses.
