AS10964 Banco Credicoop Cooperativo Limitado

AS10964 belongs to Banco Credicoop Cooperativo Limitado, Argentina's largest cooperative bank. RIS observes 7 IPv4 prefixes covering 4,096 addresses, no IPv6, and 2 observed neighbours. Reverse DNS on the sampled addresses returns bancocredicoop.coop across most of the space, with banca.rcc.com.ar and rccts5.rcc.com.ar appearing alongside it.

What it's used for

This is a bank running its own network. The whole footprint is one 200.31.224.0/20 announced as an aggregate and then broken into a /21, a /22 and four /24s. Four thousand addresses across two upstreams is the shape of an enterprise that wants provider redundancy for its online-banking and branch systems and nothing more. The first-party reverse DNS is the key evidence: the address space carries the bank's own services rather than being reassigned to customers or third parties.

Notable

The consistency of the PTRs matters. When every sampled address in a block answers with the holder's own domain, you can be confident the routing and the ownership line up, which is not something that can be assumed from the registry alone.

Interesting

Credicoop is a cooperative rather than a shareholder-owned bank, organised around member associates, and it is one of the few institutions of that form to reach national scale in Argentina. Its .coop domain, still used in reverse DNS here, is a small piece of that identity showing up in the routing infrastructure.
