United States · AI-generated

business infrastructure enterprise

An electric cooperative with its own AS number, announcing a /24 that belongs to its transit provider.

What it's used for

  • A rural electric cooperative's network. 256 addresses in one IPv4 prefix, 38.19.184.0/24, two observed BGP neighbours, and no IPv6 announced.

Notable

  • The block is netname COGENT-A, registered to a transit provider rather than to the cooperative.
  • First seen in the routing archive on 2001-06-21, an actual date rather than the archive's start.
  • Three addresses were queried for reverse DNS and none returned a name.

Interesting

  • Announcing provider space under your own number is a common halfway arrangement, and it has a catch. The number moves with you and the addresses do not, so the day the transit contract ends, every firewall rule and remote access list that mentions this range has to be rewritten.
  • An electric cooperative is member owned and runs its own poles, substations and increasingly its own fibre. Having an AS number at all says the utility decided its connectivity was infrastructure rather than a service it buys, even while the addresses are still rented.
  • Being in the routing archive since 2001 makes this one of the earlier utilities to appear there, well before metering and grid telemetry gave them an obvious reason.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-12, 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: 453 networks and 1,848 prefixes, as published 2026-11-12. 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.
