Summary
Iron Mountain
business storage corporate internal
The AS handle IRON-MOUNTAIN is operated by Iron Mountain Inc.
What it's used for
- The address space carries corporate network services, as indicated by netnames such as
IRONMOUNTAIN-216-229-144-0andIRONMOUNTAIN-208-66-136-0associated with the registrant "Iron Mountain Inc; Network Services". - With 5120 IPv4 addresses announced across 11 prefixes and only 5 observed neighbours, the inventory reflects an internal corporate estate rather than a transit or access network, consistent with Iron Mountain's role as a records management and information services provider.
Notable
- All registrants in the RDAP data align with the announcer, listing variations of "Iron Mountain Inc" or "Iron Mountain Inc. -Corp US-" for every prefix.
- The address inventory is finely subdivided into multiple /22, /23, and /24 blocks, suggesting site-by-site segmentation typical of a large enterprise with distributed facilities.
- No IPv6 prefixes are announced in the inventory.

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 1,779 prefixes, as published 2026-10-21. 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.
