Summary
Electric Reliability Council of Texas (ERCOT)
business enterprise critical-infrastructure grid-operator texas
ERCOT-ISO is the network of the Electric Reliability Council of Texas, the independent system operator that runs the Texas electric grid — scheduling generation, clearing the wholesale market and keeping the interconnection in balance for most of the state.
What it's used for
ERCOT's own corporate and market-facing systems: the public web presence, the market-participant portals that generators, retailers and utilities log into, and the internet edge of an organisation whose real work happens on private, out-of-band control networks that never appear in BGP.
Notable
Classified business (enterprise), deliberately, and the reasoning is worth stating because the obvious call is government. ERCOT is not a state agency: it is a membership-based 501(c)(4) nonprofit corporation, governed by its own 12-member board, that happens to be overseen by the Public Utility Commission of Texas and the legislature. Its members are private generators, co-ops, retailers and municipal utilities. Quasi-public function, private corporate entity — and the network is that entity's.
Routing confirms an enterprise, not an operator. RIS observes 5 IPv4 prefixes carrying 1,024 addresses — a single 66.128.16.0/22 plus its four constituent /24s, announced separately — behind 2 BGP neighbours. One small block, deaggregated for path steering across two upstreams, is the signature of an organisation that consumes connectivity for itself.
Interesting
A /22 is a startlingly small internet footprint for the operator of a grid serving 27 million people. That is the point: the SCADA and market-settlement systems that actually matter are deliberately kept off the public internet, so almost nothing of ERCOT's true scale is visible in the routing table.

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 2026-10-26, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
