Summary
State Street Bank and Trust Company
enterprise legacy
The network of State Street Bank and Trust Company (SSB-ASN-3738), the Boston custody bank and asset servicer, registered in North Quincy, Massachusetts.
What it's used for
- Corporate and financial-services networking for State Street — internal systems, offices, and the connectivity behind its custody, trading, and asset-servicing platforms.
Notable
- Enterprise address space in a heavily regulated sector: the IPs serve one institution's own infrastructure and its counterparties, never consumers.
- The AS announces a large number of small prefixes (mostly
/24s out of192.250.0.0/16), the fine-grained slicing typical of a bank running many segregated networks and extranet connections.
Interesting
- State Street has held ARIN organisation records since the early 1990s — banks were among the first non-academic institutions to build serious IP networks, driven by market-data and interbank connectivity rather than the web.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
8 upstream, 0 downstream and 8 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
