United States · AI-generated

enterprise legacy

FACTSET is FactSet Research Systems, Inc., the financial-data and analytics company headquartered in Norwalk, Connecticut. It supplies market data, portfolio analytics and research workstations to investment professionals, and has held this AS number since 1996.

What it's used for

  • FactSet's own corporate and product infrastructure: the systems that deliver its data platform and workstation to client firms.
  • Announces a small set of prefixes, most from 164.55.0.0 — a few thousand IPv4 addresses in total.

Notable

This is enterprise address space, not an ISP or a public cloud. The addresses front FactSet's own services and client-facing delivery infrastructure; there are no subscriber pools and no reseller customers. Because financial-data platforms are consumed over dedicated connections as well as the public internet, traffic here skews toward a modest number of institutional counterparties rather than a broad consumer base.

The low AS number reflects a 1996 ARIN registration — FactSet was already an established data vendor when it took its own routing identity.
