Summary
Heartland Business Systems
business it-services wisconsin
HBS-AS is operated by Heartland Business Systems, a Wisconsin-based IT services and cybersecurity firm.
What it's used for
- The address space carries corporate infrastructure, with netnames
HBS-NETWORK-001andMC-2903indicating internal network segments and acquired assets. - The AS announces 4352 IPv4 addresses across 2 prefixes and maintains 3 observed neighbours, a ratio consistent with a business network rather than a transit or large-scale access provider.
Notable
- Registrants align with the announcer for the primary block, while the smaller prefix
205.196.1.0/24is registered to Midwest Computech, Inc., reflecting the company's acquisition of that entity. - Heartland Business Systems acquired Midwest Computech, an IT service and cybersecurity company founded in 1982, integrating its address space into the HBS-AS inventory.
- The inventory consists of one large /20 block and one /24 block, with no IPv6 prefixes announced.

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 2026-10-24, 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 1,779 prefixes, as published 2026-10-24. 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.
