MAC address vendor

Red Lion Controls, LP — 4 prefixes (MA-L)

Primary prefix
00:60:DA
Block
MA-L
Status
Active

Summary

// what this is
Red Lion Controls, LP is registered to MAC prefix 00:60:DA and 3 more in the IEEE OUI database. When a device's MAC address begins with 00:60:DA, that block was registered by Red Lion Controls, LP — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Devices bearing these OUIs are OT/ICS hardware (HMIs, RTUs, industrial switches, remote-access routers) deployed on industrial/utility/manufacturing network segments, not typical consumer or office IT — treat with ICS-appropriate network isolation given the CISA advisory history.

About this vendor.

Updated  ·  Confidence: High

A MAC address starting 00:60:DA, 00:A0:1D, 00:13:47, or 00:07:AF belongs to Red Lion Controls, LP, an industrial automation manufacturer — so the hardware is almost always operational-technology (OT) or industrial-control-system (ICS) gear, not a consumer device or a typical office network endpoint.

Red Lion is a real, multi-decade industrial-networking vendor now operating as a brand of HMS Networks (redlion.net 301-redirects to hms-networks.com/red-lion, confirming the corporate lineage). Its product line spans touchscreen HMIs (Graphite Series, CR3000 Series), Crimson-configured HMI/RTU platforms, Sixnet-brand RTUs and managed industrial Ethernet switches, N-Tron managed Layer 2 switches, and cellular/Ethernet remote-access routers such as the RA70S.

Holding four separate IEEE MA-L blocks plus documented product lines and a multi-year CISA ICS-CERT advisory history is well past the "bare single-OUI registration" line — this is a substantive, identifiable company, not a shell. CISA has published at least six advisories against Red Lion/Sixnet/Crimson-based products, including a CVSS 10.0 unauthenticated remote-code-execution class of flaws in Sixnet RTUs; CISA's standing guidance for these is to isolate affected ICS devices from the public internet.

Two caveats worth flagging. First, a related legal-name string, "Red Lion Controls Inc.", separately holds its own OUI (00:05:E4) on third-party aggregator listings — treated here as a distinct IEEE record, not merged into this entry. Second, per-prefix "registration dates" shown by aggregator sites (e.g. maclookup.app, cleancss.com) are database artifacts, not IEEE facts — IEEE's own public OUI registry publishes no assignment-date field at all.

Related entity
"Red Lion Controls Inc." holds a separate OUI 00:05:E4 on aggregator listings — distinct IEEE record, not merged [Likely] — maclookup.app
Registration date
Unknown — IEEE's public OUI registry publishes no assignment-date field; third-party "registration dates" (e.g. 1998-04-22, 2001-10-24, 2005-01-23) are aggregator database artifacts, not IEEE facts [Confirmed absence] — standards.ieee.org/products-programs/regauth
Analyst note
multiple OUI blocks + documented product lines + a substantial CISA advisory history clear the vendor-shell abstention bar — this is a real, identifiable industrial-automation manufacturer, not a bare orphan registration.
