Unclassified ARIN Cable/DSL/ISP
Summary
NTT DATA Corporation
enterprise legacy
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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-17. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
