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.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
