business healthcare radiology teleradiology
ONRADINC is the autonomous system for Onrad, Inc.
What it's used for
- The space carries corporate infrastructure for a teleradiology provider, with the netname
ONRAD-1assigned to the single announced prefix. - The AS announces 512 IPv4 addresses within one prefix (
66.220.42.0/23) and maintains 3 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider. - Traffic from this AS consists of internal business operations for a healthcare company providing radiology services, including teleradiology and managed services for physician corporations.
Notable
- The RDAP registrant
Onrad, Inc.matches the AS holder, confirming consistent ownership of the address space. - Onrad, Inc. is a technology-enabled radiology provider headquartered in Phoenix, Arizona, and is recognized as the largest independent teleradiology services company in the United States.
- The address inventory is minimal, consisting of a single /23 block, which aligns with the needs of a specialized service provider rather than a large-scale ISP or hosting facility.

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 2026-10-26, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
