Lyngsoe Systems is a Danish RFID and IoT automation vendor whose MA-L block C8:9E:61 is registered to "Lyngsoe Systems LTd" at 101 Simona Dr., Unit 2, Bolton, Ontario, Canada — the firm's North American operation, even though the company itself is headquartered in Aars, North Jutland, Denmark. The company traces to 1952 as a division of Søren T. Lyngsø AS and became independent through a 1994 management buyout. The hardware behind this prefix is OT/IoT-class, not enterprise networking gear: RFID readers and portals for airport baggage handling (IATA-compliant tracking), library self-service and material management, parcel and postal sorting, and hospital RTLS asset tracking. Representative devices include the PRX23 RFID reader (10/100 Ethernet with Auto-MDIX, optional PoE, plus RS485 multi-drop serial) and the LS4550 RTLS portal (LAN Ethernet with optional LTE from Q3 2021), alongside airport-specific BagDrop, Sortation, and belt-loader readers. The FCC grantee code is PQG. For asset classification this matters because these are network-connected endpoints in sensitive venues — airports, hospitals, libraries — yet the public PRX23 manual documents no authentication, TLS, or access control on the Ethernet interface; configuration is local USB console only. No public CVEs or CISA ICS-CERT advisories were found as of June 2026, but absence of advisories is not a positive attestation of hardening. As always with OUI work, the IEEE publishes no assignment date for this block, so any third-party "date registered" is a database artifact, not an IEEE fact.
- IEEE assignment
- C8:9E:61 → Lyngsoe Systems LTd, 101 Simona Dr., Unit 2, Bolton, Ontario, CA L7E 4E8 [Confirmed] — IEEE MA-L (oui.csv line 619)
- Registry / block size
- MA-L (24-bit OUI; ~16.7M addresses per block) [Confirmed] — IEEE MA-L. NOTE: IEEE's public OUI data publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools is a database artifact, not an IEEE fact.

- PQG [Confirmed] — fccid.io/PQG-PRX23, fccid.io/PQG-LS4550
- Security context
- no public CVEs or CISA ICS-CERT advisories found (June 2026); PRX23 manual documents no auth/TLS/access-control on Ethernet, config via local USB only; OT/IoT devices in sensitive venues (airports/hospitals/libraries). Absence of advisories ≠ attestation of hardening [Confirmed on no-CVE search result; security posture is inference from public manuals] — usermanual.wiki PRX23, cisa.gov ICS advisories
- Allocated date
- Unknown — IEEE publishes no registration dates for OUI/MA-L assignments [Confirmed null] — standards.ieee.org/products-programs/regauth/oui
- Analyst note
- a globally-administered C8:9E:61 (or 78:D4:F1) MAC identifies genuine Lyngsoe RFID infrastructure; surfacing one on an airport, hospital, or library network is a network-segmentation signal worth confirming, given the lack of documented interface authentication.
