Summary

Railcar Management Inc

United States of America · AI-generated

business corporate internal

The AS handle RMI-NETWORK-ATLANTA is held by Railcar Management Inc.

What it's used for

  • The address space carries corporate infrastructure for Railcar Management, LLC, as indicated by the netnames RMI-NETWORK and RMI-NETWORK-NSPI and the reverse DNS entry rmiondemand.com.
  • The network announces 768 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio that implies an internal corporate estate rather than a transit or access provider.

Notable

  • Registrants for both announced prefixes are listed as Railcar Management, LLC, with the smaller prefix also listing RMI Administrators, which aligns with the AS holder.
  • The address inventory consists of two distinct IPv4 blocks: 208.67.24.0/23 and 204.10.22.0/24, with no IPv6 prefixes in inventory.

Reputation

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
