Summary
NTT Indonesia
hosting datacenter colocation enterprise
NTT-NET-ID-AS is PT. NTT Indonesia, the Indonesian arm of the NTT group, which operates the Jakarta 2 and Jakarta 3 data-centre campuses and sells colocation, managed hosting, cloud and network services to enterprises there.
What it's used for
- Serving the customer estate inside NTT's Indonesian facilities: colocation and managed-hosting tenants, cloud on-ramps and the enterprise circuits that terminate in Jakarta.
- RIS sees 19 IPv4 prefixes covering 40,960 addresses plus one IPv6 prefix,
2404:c8::/32. The v4 space is built on two substantial legacy blocks,119.11.128.0/17and202.171.0.0/19, sliced into /18s, /20s and a long tail of /24s. Carving a /17 into individually announced /24s is what an operator does when different customers in different racks need their space steered independently.
Notable
- Hosting and data-centre infrastructure, not a consumer ISP and not a transit carrier. The 29 observed BGP neighbours are the key number. That is an order of magnitude too few for a wholesale transit business (which peers with hundreds to thousands of ASes) but far more than an end-site enterprise, which sees a handful. Two dozen-plus adjacencies is exactly what a data-centre operator accumulates by sitting on an exchange fabric alongside the telcos, ISPs and cloud edges that its tenants want to reach.
- Note the trap in the name. NTT here is the holder, not merely the rDNS. The usual warning is that a PTR under a big carrier's domain proves nothing about ownership, but in this case the registry itself records the NTT group entity, and the space is a distinct Indonesian operation rather than NTT's Global IP Network.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
