Summary
Jack Henry & Associates, Inc.
finance business enterprise
Thirty-five announcements, two netnames, and one of those netnames records the team that filed it rather than what it holds.
What it's used for
- A core banking software company's network. 16,640 addresses across 35 IPv4 prefixes, with 20 observed BGP neighbours and no IPv6 announced.
Notable
- Most blocks carry the netname
JHA-1, registered toJack Henry & Associates, Inc. - Three carry
JHA-NETENG1, on blocks from a different range. - The space is cut very fine:
/21at the largest, then/22s,/23s and a long run of single/24s, nearly all from52.128. - Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
NETENGis a network engineering group. Somebody registered a block under their own team's name, which happens when the request comes from operations rather than from whoever owns the addresses, and nobody ever corrects it.- Thirty-five announcements from 16,640 addresses is roughly one route per
/23. That granularity only makes sense if each piece is delivered somewhere different, which for a company processing transactions on behalf of banks means one route per institution or per data centre. - Twenty neighbours is high for a network that publishes nothing. The company's customers reach it directly rather than across the open internet, and each of those arrangements is an adjacency.
- Publishing no reverse names and no IPv6 while announcing 35 prefixes is a network built to be connected to, not found.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
19 upstream, 0 downstream and 19 adjacent networks observed; most-used upstreams first.
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
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 1,784 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.
