business cooperative finance brazil

AS52671 is held by Confederacao Nacional das Cooperativas do Sicoob.

What it's used for

  • The space carries corporate infrastructure for the Sicoob cooperative credit system, as indicated by the registrant netname 194887 and the holder's identity as a national federation of credit cooperatives.
  • The AS announces 2048 IPv4 addresses within a single /21 prefix and 43 IPv6 prefixes, while maintaining only 5 observed neighbours. This low neighbour count relative to the address inventory indicates an internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal office workers, web/API endpoints, and backhaul connections for the cooperative's financial operations across Brazil.

Notable

  • The RDAP registrant Confederação Nacional das Cooperativas do Sicoob matches the AS holder name exactly.
  • The address inventory is composed of one contiguous IPv4 block and a large, finely subdivided IPv6 allocation under the 2804:c14::/35 range, consistent with site-by-site segmentation for a large organization.

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 1,778 prefixes, as published 2026-10-20. 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.
