United States · AI-generated

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 of 192.250.0.0/16), 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.
