About this network

ODN ("Open Data Network", INFOSPHERE/odn.ad.jp) is a long-running Japanese consumer ISP now operated by SoftBank Corp., inherited from the former Japan Telecom.

What it's used for

• Residential and small-business internet access in Japan (DSL and fibre), one of SoftBank's fixed-line consumer brands.

Notable

• An "eyeball" network: addresses here are home connections in Japan, not servers.
• Part of SoftBank's fixed-line portfolio; SoftBank also runs mobile and other fixed broadband networks under separate ASNs.

Interesting

• The odn.ad.jp domain dates to the early Japanese dial-up/DSL era, when Open Data Network was one of the country's better-known consumer providers.
