Summary
Instinet
enterprise legacy
Corporate ASN (INSTINET-AS) of Instinet, the New York-headquartered institutional agency broker and electronic-trading firm, today the execution services arm of Japan's Nomura Group.
What it's used for
- Financial-market networking: order routing, execution platforms, market-data feeds, and connectivity to exchanges, dark pools, and institutional clients.
- Announces a sizeable block of legacy IPv4 space supporting trading infrastructure and corporate systems across its global offices.
Notable
- This is finance-industry address space, not a service provider. Hosts here are trading systems and the private connectivity around them, and much of the network's real work happens over dedicated circuits and exchange cross-connects rather than the public internet.
- Instinet was an electronic trading venue long before "electronic trading" was the norm, which is why it appears this far down the AS-number space.
Interesting
- Nomura acquired Instinet in 2007 and runs it as an independent subsidiary, so the ASN and its handle have outlived several changes of ownership.

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 2026-10-26, 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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
