Unclassified ARIN
Summary
Stacks Inc
hosting legacy
STACKSINC-GLOBAL is operated by Stacks Inc, a small network and internet services company based in Denver, Colorado (stacksinc.net).
What it's used for
- Stacks Inc's PeeringDB record lists the network as a mix of Cable/DSL/ISP, enterprise, and network services with a global scope; the company markets high-speed internet and IPTV to home and business customers.
- AS5068 announces roughly 1,280 IPv4 addresses. The company also operates AS398704 (
STACKSINC-BACKBONE).
Notable
- The low number is a reissue: ARIN registered AS5068 to Stacks Inc in 2024, and the organization record only dates to 2020. There is no early-internet lineage here.
Interesting
- Name trap: Stacks Inc is unrelated to STACK Infrastructure, the hyperscale data center operator, despite both being associated with Denver.

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 2026-10-13, 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: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
1 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
