Summary

Marubeni Network Solutions Inc.

Japan · AI-generated

enterprise legacy

PTOP — registered to Marubeni OKI Network Solutions Inc., the network integration company now known as Marubeni Network Solutions Inc.

What it's used for

  • Network design, build, monitoring, and operation for corporate customers inside and outside the Marubeni group — a managed-network business rather than a public ISP.

Notable

  • The company was a Marubeni/OKI joint venture until 2019, when Marubeni bought out OKI Electric's stake and dropped "OKI" from the name. The registry entry still carries the older company name, a common lag between corporate reality and RIR records.
  • Marubeni is one of Japan's largest general trading houses (sogo shosha); this ASN belongs to its IT/network solutions arm, not to the trading business.

Reputation

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 1,778 prefixes, as published 2026-10-20. 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.
