Summary
Parsec Data Management
hosting enterprise legacy
PDM is Parsec Data Management Inc., a commercial data centre and managed services provider in Billings, Montana. The AS carries its colocation, cloud, and IaaS customers.
What it's used for
- Hosting: colocation, virtual infrastructure, disaster recovery, and managed services (firewalls, intrusion prevention) out of a single Montana facility. RIS sees 11 announced IPv4 prefixes totalling 2,560 addresses, one IPv6 prefix (
2602:fff3::/36), and 4 observed BGP neighbours. - The four neighbours matter. A hosting company that is also a transit business would peer widely; Parsec peers with a handful of upstreams, so the AS exists to give the data centre its own multihomed, provider-independent presence rather than to sell transit onward.
Notable
- Every sampled address answers under
parsecdata.com, in the plain162-253-12-5.parsecdata.commachine-generated form, with one host standing out ascloudadmin.parsecdata.com. First-party reverse DNS across the whole inventory is the strongest available evidence that the holder actually operates this space rather than leasing it out, and it is what separates a real hosting operator from an AS number wrapped around somebody else's addresses. - The prefix registrants agree: all of them resolve to Parsec Data Management under handles like
PDM-BLNGMT-A1,-A2,-A3. Those handles are simply the company's Billings, MT allocations, numbered in order of acquisition.
Interesting
- The inventory is a scatter of /22s and /24s across
162.218.100.0/22,162.253.12.0/22,192.103.12.0/24and208.38.220.0/24, announced both as aggregates and as component /24s. That shape is normal for a small operator that grew by picking up blocks as they became available, and it is not by itself a leasing signal when every block is self-registered and self-named in DNS.

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
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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.
