Summary
oneZero Financial Systems
finance enterprise infrastructure
The AS is filed under a handle that names a cabinet in a particular exchange building.
What it's used for
- A financial technology company's network. 4,096 addresses across seven IPv4 prefixes, with three observed BGP neighbours and no IPv6 announced.
Notable
- The AS handle is
ITHS-NY4-BLK-001, which matches neither the company name nor any netname on its blocks. - Five of the seven blocks share the single netname
OFSL-5; a sixth carriesONEZERO-ADDRESS-BLOCK-1. 38.76.4.0/24is registered toCogent Communications, LLCunderCOGENT-A.- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- That handle reads as a facility, a building code and a numbered block. The building code in the middle is one of a handful of addresses in the financial world that everyone in the industry can name from memory, because being inside it is the difference between a trade arriving first and arriving second. The AS was registered by whoever ran the cage, and the name stuck.
- Five blocks under one netname numbered five is a company that filed once, was given space repeatedly, and reused the same label. The sixth block breaks the pattern with a fully spelled-out name, which is what happens when a different person does the paperwork.
- One block is the carrier's own space, announced by the customer. That is how a provider hands out a small assignment without the customer having to justify it to a registry.
- Nothing answers a reverse lookup across eighteen addresses, which for trading infrastructure is the point.

Internet exchanges
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 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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 1,783 prefixes, as published 2026-10-17. 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.
