Summary
Southern California Edison
enterprise legacy
SCE, the network of Southern California Edison, the electric utility serving most of central, coastal and southern California outside Los Angeles city limits. Headquartered in Rosemead, California.
What it's used for
- SCE's own corporate and operational networking: offices, generation and distribution facilities, and the systems that run the grid.
- Announces a small number of very large legacy blocks, including
192.212.0.0/15,155.13.0.0/16,163.236.0.0/16and192.214.64.0/19, well over a quarter of a million IPv4 addresses.
Notable
- The address space is enormous relative to the number of prefixes and carries essentially no public reverse DNS. That is the fingerprint of a utility: a very large private-facing estate (substations, SCADA-adjacent corporate systems, field and metering infrastructure) with only a thin public edge.
- This is an enterprise network, not a service provider. None of the space is sold to subscribers.
Interesting
- Big US utilities were among the earliest non-academic organisations to obtain large address allocations, since they already ran extensive private data networks for grid operations before the commercial internet existed. The legacy /15 and two /16s here are a relic of that era.

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 1,783 prefixes, as published 2026-10-17. 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.
