Summary
STNet (Pikara)
isp eyeball legacy
STCN — STNet, Incorporated, the telecom arm of the Shikoku Electric Power
group, based in Takamatsu. It runs Pikara, the fibre broadband service used
across Japan's Shikoku island.
What it's used for
- Consumer and business fibre (FTTH) internet access in the four Shikoku prefectures: Kagawa, Tokushima, Ehime and Kochi.
- STNet's own data-centre, system-integration and corporate network services.
Notable
- An eyeball network: the ~595k IPv4 addresses across ~50 prefixes resolve overwhelmingly to subscriber space named
opt-IP-ADDR.client.pikara.ne.jp, which is Pikara's FTTH customer pool. Addresses here belong to homes and small businesses on Shikoku, not to servers. - Geographically well-behaved for a Japanese ISP: it is a regional operator, so its space really does concentrate in one part of the country rather than being spread nationally like NTT's or SoftBank's.
Interesting
- STNet is one of several Japanese ISPs founded by a regional electric utility to monetise the fibre it had already strung for grid telemetry. The same pattern produced TOHKnet ([AS7516](https://asn.ipinfo.app/AS7516)) in Tohoku.
