About this network

INTERVIA — a network of NTT DATA Corporation, the systems-integration and IT-services company of the NTT group.

What it's used for

• Corporate networking and the delivery of NTT DATA's managed IT and system-integration services to Japanese enterprise and public-sector clients.

Notable

• NTT DATA is the IT services arm of NTT — not to be confused with the group's carrier networks: AS2914 is NTT's global IP transit backbone and AS4713 is the OCN consumer ISP. An IP here belongs to the systems integrator.
• Addresses in this space typically front business systems that NTT DATA builds or operates for a client, so the visible organisation may not be the one whose service you are actually reaching.
