Summary

Japan · AI-generated

isp enterprise legacy

U-NETSURF — UNIADEX, Ltd., a Japanese IT infrastructure services company

in the BIPROGY (formerly Nihon Unisys) group, and the operator of the

U-netSURF internet service.

What it's used for

  • U-netSURF internet connectivity, mail and web outsourcing, and related managed services, sold largely to Japanese businesses.
  • UNIADEX's own IT infrastructure and integration work.

Notable

  • A corporate-leaning ISP: U-netSURF has run since the mid-1990s and rides on NTT East/West FLET'S fibre access rather than on UNIADEX-owned last mile.
  • The address space mixes access customers with hosted services (mail, web, certificates), so it is not a pure eyeball network.
