isp residential cooperative argentina

AS52323 is operated by Colsecor Cooperativa Limitada.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS names such as host255-175.16.181.colsecor.net.ar and reserved.181.16.134-254.colsecor.net.ar.
  • The AS announces 29,696 IPv4 addresses across 24 prefixes and 43 IPv6 prefixes, with 24 observed neighbours, indicating a local access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for the cooperative's member base in the Calchín region of Argentina.

Notable

  • Registrants for the majority of prefixes are Colsecor Cooperativa Limitada or Cooperativa de Provisión COLSECOR Ltda, while one prefix (138.118.208.0/22) is registered to COOPERATIVA DE ELECTRICIDAD OYSP DE CALCHIN LTDA..
  • The inventory is concentrated in the 181.16.128.0/17 range, with a single smaller block in 138.118.208.0/22.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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.
