Summary
A-Bone (Internet Initiative Japan)
transit legacy
ABONE-AS — A-Bone, the pan-Asian internet backbone operated by Internet
Initiative Japan (IIJ).
What it's used for
- International backbone and transit connectivity between Asia-Pacific networks and the wider internet.
- Infrastructure and interconnection rather than end-user address space — the ASN announces only a small amount of IPv4.
Notable
- A-Bone ("Asia Internet Backbone") was built in the mid-1990s to link Japan, Hong Kong, Singapore, and the United States with what were then high-speed circuits, at a time when most Asian networks reached each other by way of the US.
- It was run through Asia Internet Holding Co., Ltd., which was later merged into IIJ.
Interesting
- IIJ was Japan's first commercial ISP, and its main network is [AS2497](https://asn.ipinfo.app/AS2497); A-Bone remains a separate ASN reflecting its origin as a distinct regional backbone project.
