Summary
Cooperativa de Servicios Públicos de Morteros
residential isp cooperative argentina
AS27976 is operated by Cooperativa de Servicios Públicos de Morteros Ltda., a local utility cooperative in Morteros, Argentina.
What it's used for
- The address space carries residential broadband access, evidenced by reverse DNS entries such as
adsl.211-63-179-255.coopmorteros.com.arandhost-179-63-210-0.isp.cspm.net.ar. - The AS announces 8192 IPv4 addresses across 5 prefixes and 28 IPv6 prefixes, while maintaining only 7 observed neighbours, a ratio indicative of an access network rather than a transit provider.
Notable
- All registrants for the announced prefixes match the announcer, consistently listed as "Coop. de Servicios Públicos de Morteros Ltda." or "Cooperativa de Servicios Publicos de Morteros Ltda".
- The inventory consists of five distinct IPv4 blocks, including /21s and /22s, alongside a fragmented set of IPv6 prefixes under the 2803:700::/41 space.

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: 453 networks and 1,854 prefixes, as published 2026-11-06. 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.
