Summary
Sony Global Solutions Inc.
enterprise legacy
AS9619 (SSD) is held by Sony Global Solutions Inc., the Sony group's in-house IT services company. It runs the systems integration, infrastructure and information-security functions that underpin Sony's corporate IT, and it exists to serve the group rather than an external customer base.
What it's used for
This is Sony's corporate network, and the reverse DNS says so plainly: every sampled address resolves under noc.sony.co.jp, with names like sw2.tdc.noc.sony.co.jp and sgwlb01.jdc.noc.sony.co.jp. Those are network-operations hostnames, switches and load balancers, tagged by data-centre site (tdc, jdc) rather than by customer. The AS announces 8 IPv4 prefixes for 200,704 addresses, and three of them are full legacy class-B /16s: 133.138.0.0/16, 146.215.0.0/16 and 137.153.0.0/16. The rest is a /20 and a handful of /24s from 211.125.128.0, plus three IPv6 blocks under 2001:cf8::/32. Four observed BGP neighbours on 200k addresses is the signature of a large enterprise buying resilient transit, not of a provider. Nothing here is sold as connectivity: the space carries Sony's own corporate estate.
Notable
- The
SSDhandle predates the current company name. Sony Global Solutions began life as Sony System Designs Inc. in 1988, and the registry handle has outlived two renamings. - Three separate class-B /16s in one enterprise AS is a strong sign of an early, pre-CIDR allocation history rather than modern RIR grants.
- Do not confuse this with Sony's consumer-facing networks. So-net's business ISP is AS9600; AS9619 is internal corporate IT.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,768 prefixes, as published 2026-10-12. 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.
