Unclassified ARIN
Summary
IDD Enterprises, LP (Fidelity National Information Services)
enterprise legacy
A 1996 ARIN registration (IDD) to IDD Enterprises, LP of Waltham,
Massachusetts. The address space it announces today is registered to Fidelity
National Information Services (FIS), the financial-technology company.
What it's used for
- Corporate and application networking inside the FIS orbit rather than any public-facing service. It announces most of
147.249.0.0/16, whose ARIN netblock is namedFIS-IDDISand is registered to Fidelity National Information Services, plus a small block namedFIS-VALDI. - Reverse DNS on the space resolves to internal-looking corporate hosts, and its transit comes largely from FIS's own AS18434 — consistent with an enterprise network, not a service provider.
Notable
- The AS still carries the historical registrant name (IDD Enterprises), while the underlying IPv4 has been re-registered to FIS. The
IDDISstring inside the netblock name is the fossil that links the two. - The registration sits in a sequential run of ARIN assignments made in April 1996, when AS numbers in the mid-6400s were being handed out in order.
