Summary
Cleveland-Cliffs Steel
enterprise legacy
The network of Cleveland-Cliffs Steel LLC (ARCEL-2), the US steelmaker, with
its registry record listed in Chicago, Illinois.
What it's used for
- Corporate and industrial networking — offices, mills, and the systems that run them.
Notable
- Enterprise address space: it serves a manufacturer's own operations, not customers or subscribers.
- Announces a small footprint, on the order of a couple of thousand IPv4 addresses.
Interesting
- The
ARCELhandle is a leftover from ArcelorMittal USA, whose US steel business Cleveland-Cliffs acquired in 2020 — the AS number moved with the assets while the registry handle stayed put, a common way a handle ends up naming a company that no longer holds it.
