Summary
FirstEnergy Corp.
utility corporate business infrastructure
FIRSTENERGY is the autonomous system for FirstEnergy Corp., a major electric utility holding company.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by the consistent netname
FE-CORPacross all sampled prefixes. - With 67,584 IPv4 addresses announced against only 3 observed neighbours, the ratio indicates a large internal corporate estate rather than a transit or access network.
Notable
- All registrants in the evidence pack are FirstEnergy Corp., fully agreeing with the AS announcer.
- The address inventory is finely subdivided into 26 IPv4 prefixes, primarily within the 148.108.0.0/16 range, reflecting site-by-site segmentation typical of a large utility's internal network.
- FirstEnergy Corp. is a publicly traded utility (NYSE: FE) serving customers in Ohio, Pennsylvania, West Virginia, New Jersey, New York, and Maryland.

Internet exchanges
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 2026-10-14, 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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
