About this network

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.
