About this network

A Société Générale autonomous system registered to the bank's Market Back Office (MARCBO), the function that settles and processes trades behind the trading desks.

What it's used for

• Corporate network capacity for the bank's market operations and settlement systems. This is private enterprise address space, not a service sold to customers.

Notable

• One of a run of adjacent ASNs the bank holds per internal division, alongside AS3295 (Technical Department), AS3296 (the main Société Générale AS) and AS3299 (International Department).
• Financial back-office networks are latency- and availability-sensitive, which is part of why a bank keeps its own routing rather than depending on a single upstream.

Interesting

• The department-level naming preserved in the registry (MARC/BO) is a small archaeological detail: allocation records from an era when internal org charts ended up in public whois.
