AS9159 Credit Agricole

AS9159 is held by Crédit Agricole SA, one of the largest banking groups in France and a major cooperative retail bank in Europe. The AS carries the group's own corporate network infrastructure.

What it's used for

The announced space is enterprise banking infrastructure: internal corporate networks, back-office systems, and connectivity for the group's operations rather than any retail-ISP or hosting product. The inventory is a handful of contiguous legacy blocks (the 158.190.0.0/16–158.192.0.0/16 run plus 134.227.0.0/16 and a couple of /24s), consistent with a large institution numbering its own estate rather than assigning customer space.

Notable

• The registered holder is Crédit Agricole SA, the listed central body of the Crédit Agricole cooperative group.
• No PTRs were returned on the addresses sampled inside the announced prefixes, which is unremarkable for private corporate networks.
• The 158.190/16–158.192/16 and 134.227/16 blocks are the sort of large early allocations that established enterprises have held for a long time, though the AS is best described by its current holder rather than any precise origin date.

Interesting

This is one of several bank-operated autonomous systems that appear in the low ASN range: a financial institution running its own AS for control over its corporate routing rather than to sell connectivity.
