Summary
Nikkei Inc.
enterprise legacy
AS9593 (NIKKEI) is held by Nikkei Inc. (Nihon Keizai Shimbun), the Tokyo-based media and publishing company behind The Nikkei, Japan's leading financial daily, and the owner of the Financial Times and the TX Network. This is a corporate enterprise AS, not a service provider.
What it's used for
The routing evidence is about as clean an enterprise signature as this range produces: a single announced IPv4 prefix, 138.101.0.0/16, for 65,536 addresses, and no IPv6 announced at all. One legacy /16 and nothing else is the classic shape of an organisation that received a class-B allocation early and has simply kept announcing it, rather than a provider that has accreted blocks from an RIR over time. The 14 observed BGP neighbours are more than a single-homed office would need but nowhere near the hundreds or thousands a wholesale carrier peers with, so this is a well-connected, multihomed corporate network buying resilient transit rather than selling it. That fits a large publisher: newsroom and editorial systems, corporate IT, and the public-facing infrastructure of a global news brand that cannot afford to be offline.
Notable
- A single class-B /16 with no IPv6 and no downstream customers means everything inside this AS is Nikkei's own. Any address in
138.101.0.0/16should be read as corporate, not as a hosting or eyeball address. - Nikkei is employee-owned. Japanese law prevents newspaper companies from being publicly traded, so the parent of the world's largest financial newspaper is itself not listed.

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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
