• Shell's own global corporate network: offices, refineries, trading operations, and the internal services that connect them.

Notable

• An enterprise network. Addresses here belong to a multinational's staff and systems, not to customers or hosted content.
• Shell's registry records are split between its Netherlands entity and a Houston address, reflecting a company with major hubs on both sides of the Atlantic.
• Carried in the registry with legacy status — the ASN predates the current RIR allocation regime and was later brought under RIPE administration.
