Argentina · AI-generated

utility residential cooperative argentina

AS27851 is operated by Cooperativa Eléctrica y de Servicios Públicos Lujánense Limitada, a local utility cooperative in Luján, Buenos Aires.

What it's used for

  • The address space carries residential and access traffic, evidenced by reverse DNS entries such as net.154.81.200.ppp.lujan-bue.coopenet.net.ar and 255.187.110.200.ppp.lujan-bue.coopenet.net.ar.
  • The AS announces 5120 IPv4 addresses across 3 prefixes and 2 IPv6 prefixes, with 7 observed neighbours, indicating a small access network serving a local community rather than a transit provider.

Notable

  • All registrants for the announced prefixes match the AS holder, COOPERATIVA ELECTRICA Y DE SERVICIOS PUBLICOS LUJANENSE LIMITADA.
  • The address inventory consists of three contiguous IPv4 blocks and two IPv6 /33 prefixes, all registered to the same cooperative entity.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 1,773 prefixes, as published 2026-10-13. 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.
