Unclassified DROP-listed space ARIN
Summary
Colocation America
hosting colocation datacenter
AS-COLOAM is operated by Colocation America Corporation.
What it's used for
- The address space carries colocation and data center infrastructure, evidenced by netnames such as
CAC-BLOCK4,US-COLOCATION-20150930, and reverse DNS entries pointing tordns.ColocationAmerica.com. - With 87,040 IPv4 addresses announced across 174 prefixes and only 4 observed neighbours, the high address-to-neighbour ratio indicates a hosting or access network rather than a transit provider.
Notable
- Registrants include
Colocation America Corporation,code200 UAB,MOD Mission Critical, andUAB, suggesting the AS aggregates space for multiple tenants or subsidiaries within the colocation ecosystem. - The inventory consists of numerous /21 and /22 blocks, including ranges in 45.73.160.0/21, 66.78.0.0/21, and 173.211.32.0/21, reflecting a finely subdivided corporate and tenant estate.

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 2026-10-31, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 447 networks and 1,845 prefixes, as published 2026-10-31. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

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