Summary
Eni
enterprise legacy
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.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
