Summary
Eze Castle Software (SS&C Eze)
business enterprise finance fintech
EZE-CASTLE-SOFTWARE-LLC is Eze Castle Software, founded 1995 and today part of SS&C Technologies as SS&C Eze after SS&C's $1.45bn acquisition in 2018. It builds order- and execution-management systems (OMS/EMS) for hedge funds and asset managers.
What it's used for
- Serving Eze's investment-management platform to buy-side clients: order routing, execution, portfolio and compliance systems, plus the remote-access gateways those clients connect through.
Notable
- Enterprise / financial-technology, not hosting and not transit. RIS sees 15 IPv4 prefixes carrying roughly 6,912 addresses, with 5 observed BGP neighbours. A software vendor's production edge looks exactly like this: a few thousand addresses, several upstreams for the redundancy trading clients demand, and nobody downstream buying transit.
- Reverse DNS identifies the equipment rather than the tenant.
bigip03-10.taltrade.com,bigip03-12,bigip03-67andbigip03-61are F5 BIG-IP load balancers — the front door of an application service, spread across four different prefixes (63.75.60.0/22,63.215.120.0/23,198.207.140.0/24).chiremote.ezesoft.comis a Chicago remote-access gateway under the company's own domain. Load balancers and remote-access endpoints are a service operator's own infrastructure; a hosting provider's space would carry unrelated customers' hostnames instead. - The prefixes are scattered across
63.x,142.0.x,193.201.x,204.213.xand74.118.x, but they are first-party and carry first-party rDNS — untidiness from acquisitions and multiple data centres, not the address-broker shape.
Interesting
taltrade.comis a legacy brand still fronting production hosts, another AS wearing its merger history in reverse DNS.

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 2026-10-29, 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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
