Summary
Affiliated Monitoring
business enterprise
Two alarm monitoring companies share one AS number, and nothing on it answers to a name.
What it's used for
- An alarm monitoring network. 2,048 addresses across six IPv4 prefixes, three observed BGP neighbours, and no IPv6 announced.
Notable
- Four blocks are registered to
Affiliated Monitoring, Inc., two of them netnameAFFILIATEDMONITORINGand two netnameAC-359. - Two are registered to
DGA Security Systems, Inc., netnamesDGASE-1andDGA-SECURITY. - The six blocks are drawn from six unrelated parts of the address space.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- One company filing under two conventions is the ordinary case.
AFFILIATEDMONITORINGspells the name out andAC-359is an internal counter, and the two sit side by side because they were filed years apart by people following different habits. - Nothing in the sample answering a reverse lookup fits the work. An alarm monitoring centre receives connections from equipment installed in customer buildings, and that equipment is configured with addresses rather than names, so a name would serve nobody.
- Six small blocks in six unrelated ranges, behind three upstreams, is a network built for staying reachable rather than for growing. For a business whose product is that the signal arrives, the redundancy is the service.

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 2026-10-20, 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 1,778 prefixes, as published 2026-10-20. 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.
