Summary
Radio Free Europe/Radio Liberty
media business us
The AS handle RFERL-ORG is held by Radio Free Europe/Radio Liberty.
What it's used for
- The address space carries infrastructure for an international media organization, with all three prefixes registered under the netname
COGENT-Aby Cogent Communications, LLC. - The AS announces 768 IPv4 addresses across 3 prefixes and maintains 4 observed neighbours, a ratio consistent with a small-scale corporate or media network rather than a transit provider.
Notable
- The RDAP registrants for all announced prefixes are Cogent Communications, LLC, which differs from the AS holder Radio Free Europe, suggesting the address space is leased or hosted via Cogent.
- The address inventory consists of three /24 blocks: 38.100.22.0/24, 38.124.237.0/24, and 38.124.238.0/24, all located in the United States.

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 2026-10-14, 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 1,773 prefixes, as published 2026-10-13. 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.
