United States of America · AI-generated

utility cooperative residential colorado

CORE-ASN is held by CORE Electric Cooperative.

What it's used for

  • The address space carries infrastructure for a member-owned electric utility, with netnames CO-SEDALIA-01 and COGENT-A observed in the inventory.
  • The AS announces 1024 IPv4 addresses across 3 prefixes and maintains 2 observed neighbours, a ratio consistent with a business network rather than a large-scale access provider.
  • Traffic from this AS represents internal corporate operations and utility infrastructure for an electric cooperative serving over 300,000 residents in central Colorado.

Notable

  • Registrants for the 38.143.229.0/24 and 38.143.233.0/24 prefixes are listed as Cogent Communications, LLC, while the 74.123.194.0/23 prefix is registered to CORE Electric Cooperative.
  • The operator was formerly known as Intermountain Rural Electric Association (IREA) before rebranding to CORE Electric Cooperative.
  • The inventory consists of three distinct IPv4 prefixes with no IPv6 announcements.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
