Summary

Cooperativa Telefónica de Capitán Bermúdez

Argentina · AI-generated

residential isp cooperative argentina

AS27877 is operated by Cooperativa Telefónica de Capitán Bermúdez, a local telecommunications cooperative in Argentina.

What it's used for

  • The address space carries residential broadband access, evidenced by the reverse DNS record adsl-200-110-165-254.netcoop.com.ar which indicates ADSL service.
  • The AS announces 8192 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining only 6 observed neighbours. This high address-to-neighbour ratio is characteristic of an access or eyeball network rather than a transit provider.

Notable

  • All registrants for the announced prefixes match the announcer, identified as Coop. Telefonica de Capitán Bermúdez.
  • The address inventory consists of three distinct IPv4 blocks: 190.123.96.0/20, 190.123.112.0/21, and 200.110.160.0/21, alongside a single large IPv6 allocation 2803:5000::/32.

Reputation

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 1,773 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.
