About this network

The corporate Autonomous System of Eni S.p.A. (ASN-ENI), the Italian multinational energy company headquartered in Rome. Eni operates across oil and gas exploration, refining, chemicals and power generation, and is one of Italy's largest companies.

What it's used for

• Eni's own global corporate network: internet edge for its offices, refineries, research centres and data centres, plus its public web presence.
• The AS announces a single legacy Class-B-sized range, 151.96.0.0/16, plus its two halves. One big contiguous block held directly by the company is the classic large-enterprise inventory.

Notable

• Enterprise space. These addresses belong to Eni and its subsidiaries; they are not sold or assigned to third parties, and there are no subscriber pools.
• Almost no reverse DNS is published on the block, which is typical for a corporate network that keeps most of the range behind firewalls and NAT and exposes only a small public service footprint.
• Eni is unusual among energy firms in running its own large HPC estate (used for seismic imaging and reservoir modelling) at its data centre in Lombardy, so its network carries research-scale compute alongside ordinary corporate IT.
