Summary

Japan Network Information Center (JPNIC)

Japan · AI-generated

legacy

PPP-EXP is held by the Japan Network Information Center (JPNIC), Japan's national internet registry, and is used for its Pool Protection Project rather than by an end-user organization.

What it's used for

  • Announcing otherwise-unused address space so that free blocks appear routed, a defensive measure against unauthorized (hijacked) announcements.

Notable

  • Operated by the registry itself (a JPNIC/IIJ effort), so this is infrastructure tooling, not a commercial ISP, host, or corporate network.
