Summary

1199SEIU National Benefit Funds

United States · AI-generated

enterprise legacy

ASN1 belongs to the 1199SEIU National Benefit Funds, the New York organisation

that administers health and benefit funds for members of the 1199SEIU healthcare

workers union.

What it's used for

  • Corporate networking for a benefits administrator — member services, claims systems, and office infrastructure.
  • A small footprint of about a thousand addresses, consistent with an organisation running its own network rather than selling connectivity.

Notable

  • Institutional address space belonging to a union benefit fund, so IPs here are staff and back-office systems rather than consumers.
  • The low AS number is not an early-internet artefact. ARIN registered both the organisation and this ASN in 2009, so the number was reclaimed and reissued to a modern holder.

Interesting

  • The ASN1 handle is one of the more misleading in the registry. It looks like a claim on the first AS number ever issued, but it simply means this holder's first (and only) AS number. The real AS1 belongs to Level 3 / Lumen — see [AS1](https://asn.ipinfo.app/AS1).
