About this network

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 named FIS-IDDIS and is registered to Fidelity National Information Services, plus a small block named FIS-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 IDDIS string 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.
