Summary

KEK (High Energy Accelerator Research Organization)

Japan · AI-generated

education research legacy

HEPNET-J is operated by KEK, the High Energy Accelerator Research Organization, a Japanese national research institute for particle and accelerator physics in Tsukuba.

What it's used for

  • Networking for high-energy physics research (HEPNET-J, the High Energy Physics Network for Japan), connecting KEK and collaborating institutions.

Notable

  • A national research-laboratory network, not a commercial ISP. The low AS number reflects an early Japanese-internet allocation tied to the physics research community.
