Summary

WIDE Project

Japan · AI-generated

education research legacy

WIDE-BB is a backbone network of the WIDE Project (Widely Integrated Distributed Environment), a long-running Japanese internet research consortium of universities and companies.

What it's used for

  • Experimental and research networking for the WIDE Project's members and testbeds.

Notable

  • A research-network address, not a commercial ISP or host. The low AS number reflects an early allocation to a pioneering research effort.

Interesting

  • WIDE was founded in 1988 under Jun Murai (often called "the father of the internet in Japan") and has operated core internet infrastructure including one of the DNS root servers.
