Unclassified ARIN
Summary
Nasdaq, Inc.
business financial exchange infrastructure
AS-ASN-3 is operated by Nasdaq, Inc., the American multinational financial services corporation and stock exchange operator.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by the registrant
Nasdaq, Inc.and netnameNET-204-190-0-0-1for both announced prefixes. - The AS announces 1024 IPv4 addresses across 2 prefixes and maintains 3 observed neighbours, a ratio indicating a small, self-contained internal network rather than a transit or access provider.
- Traffic from this AS consists of internal corporate systems, market data services, and exchange infrastructure supporting Nasdaq's global trading and analytics operations.
Notable
- Registrants for both prefixes match the AS holder,
Nasdaq, Inc., confirming direct ownership of the address space. - The address inventory is compact and finely subdivided into two /23 blocks, consistent with an internal corporate estate segmented for operational isolation.

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 2026-10-15, 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 1,782 prefixes, as published 2026-10-16. 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.
