Summary
Goldman Sachs International
enterprise finance legacy
AS9084 (GSI-AS) is registered to Goldman Sachs International, the London-based European arm of the Goldman Sachs investment bank.
What it's used for
This is corporate/enterprise infrastructure for a global financial institution, not a service-provider network. The AS announces around 17 small IPv4 prefixes (about 4,352 addresses) drawn from 204.4.128.0-region and 154.1.0.0-region blocks, homed to just two observed BGP neighbours. That shape (many /24s, minimal peering) is typical of an enterprise multihoming its own office and trading connectivity rather than routing customer traffic.
Notable
The space has been announced since 2000. The addresses back Goldman Sachs' internal networks, market-data connectivity and trading systems; no PTRs were returned on the addresses sampled, consistent with locked-down corporate infrastructure.
Interesting
Financial firms commonly run their own AS purely to control routing to exchanges, market-data feeds and counterparties over dedicated links, which is what the tiny neighbour count here reflects.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-03, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 448 networks and 1,851 prefixes, as published 2026-11-04. 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.
