isp cooperative residential argentina

AS27987 is operated by NODOCOOP Federación de Cooperativas Ltda., a federation of cooperatives in Argentina.

What it's used for

  • The address space carries residential access traffic, evidenced by reverse DNS entries such as cmodem.190-103-193-255.celt.com.ar, adsl.190-103-202-254.coopespartillar.com.ar, and client-186-190-183-126.sanjosecoop.com.ar.
  • The AS announces 7168 IPv4 addresses across 13 prefixes and 1 IPv6 prefix, with 9 observed neighbours. This ratio of address space to peering partners indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants include NODOCOOP Federación de Cooperativas Ltda., Cooperativa Electrica de Tornquist LTDA, Cooperativa de Servicios Públicos de San Jose LTDA, Cooperativa de Huanguelén Ltda., and Cooperativa de Servicios Públicos de San Miguel Arcángel Ltda., reflecting the federated structure of the operator.
  • The inventory consists of multiple /22, /23, and /24 blocks, primarily in the 186.190.0.0/16, 190.103.0.0/16, and 181.189.0.0/16 ranges, along with a single /32 IPv6 block.

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 1,784 prefixes, as published 2026-10-19. 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.
