About this network

INFOWEB is Fujitsu Limited's consumer internet service, one of Japan's early dial-up and broadband ISPs. The InfoWeb brand later folded into the @nifty service.

What it's used for

• Consumer internet access for subscribers across Japan.

Notable

• A large eyeball access network (over a million IPv4 addresses), serving end users rather than acting as a hosting or transit provider. The low AS number reflects an early Japanese-internet allocation.
