Summary
ITOCHU Techno-Solutions (CTC)
legacy hosting enterprise
AS9993 (CTC-ODC) is held by ITOCHU Techno-Solutions Corporation (伊藤忠テクノソリューションズ, CTC), a large listed Japanese systems integrator in the ITOCHU group. The ODC in the handle stands for its outsourcing/data-centre business, and that is what this AS carries: CTC runs its own data centres and sells cloud, hosting and managed outsourcing out of them.
What it's used for
The reverse DNS settles the question. A sampled address in 220.152.120.0/21 resolves under technocuvic.com — TechnoCUVIC being CTC's own hosted/virtual infrastructure service brand — so the space is demonstrably carrying CTC's commercial hosting platform rather than just corporate offices.
The routing shape agrees. RIS sees 9 announced IPv4 prefixes totalling 91,136 addresses, one IPv6 aggregate (2402:1400::/32, a full ISP-sized allocation), and 27 observed BGP neighbours. That neighbour count is the discriminator: far more than the one-or-two upstreams of an enterprise that merely consumes transit, and far fewer than the hundreds a wholesale carrier would show. Two dozen adjacencies is what a data-centre operator builds — several transit providers plus peering at Japanese exchanges, to give hosted customers good paths.
The prefix mix reflects a long history: a legacy 157.113.0.0/16 at the core, plus a scatter of /19s through /22s in 202/203/211/220/27/182 space accumulated over the years.
Notable
- CTC is a publicly traded subsidiary of the ITOCHU trading house, and its IPO capitalisation famously exceeded that of its parent at the time.
- Treat this as an IDC/hosting network. Addresses here belong to CTC's customers' workloads, not to CTC staff.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
