About this network

The corporate network of Goldman Sachs, the New York investment bank (GSCO, short for Goldman, Sachs & Co.). Registered to The Goldman Sachs Group, Inc. at 200 West Street, Manhattan.

What it's used for

• Enterprise connectivity for a global investment bank: internal systems, trading and market-data infrastructure, and public-facing services.
• Announces a modest set of /24s rather than a large block — typical of a firm that needs presence, not scale, on the public internet.

Notable

• This is a financial institution's own network, not a service provider. None of the address space is sold or resold; it exists to carry Goldman's own traffic.
• Reverse DNS is essentially absent across the announced prefixes, which is common for banks that deliberately minimise what the outside world can enumerate.

Interesting

• A four-digit AS number in the 6100s dates the registration to the mid-1990s, when large US financial firms were among the first non-academic organisations to take their own address space and routing identity.
