MAC address vendor

Demant Enterprise A/S — 2 prefixes (MA-L)

Primary prefix
84:49:EE
Block
MA-L
Status
Active

Summary

// what this is
Demant Enterprise A/S is registered to MAC prefix 84:49:EE and 1 more in the IEEE OUI database. When a device's MAC address begins with 84:49:EE, that block was registered by Demant Enterprise A/S — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Globally-administered Demant Enterprise OUI = genuine EPOS-era enterprise audio hardware; post-2024 these may ship under ACCO Brands, so registered org and current owner can diverge.

About this vendor.

Updated  ·  Confidence: High

Demant Enterprise A/S is a Danish legal entity that holds two IEEE MA-L (24-bit OUI) blocks — 84:49:EE and 98:D9:3D — both registered to the same address at Kongebakken 9, Smørum 2765, Denmark. The entity sits inside the Demant A/S group, a hearing-healthcare and audio-technology conglomerate headquartered in Smørum and founded in 1904. The "Demant Enterprise" name maps to the EPOS brand of professional enterprise audio: DECT and Bluetooth wireless headsets, speakerphones, and meeting-room audio built for unified communications and contact centers, with certified compatibility for Microsoft Teams, Cisco Webex, Zoom, and Google Meet. A useful caveat for asset classification: Demant divested EPOS to ACCO Brands across 2024–2025 as it refocused on hearing healthcare, so the registering legal entity predates that divestiture and devices on these OUIs may now be marketed under a different corporate owner. Note also the distinct entity "Demant A/S" (without "Enterprise"), which holds separate OUIs (00:19:8E, 00:F8:71) and is not covered by this entry. IEEE publishes no registration dates for OUI prefixes, so any "date registered" seen on third-party lookup tools is a database artifact, not an IEEE fact.

No IEEE date
IEEE public OUI data (Registry, Assignment, Organization Name, Organization Address) publishes NO registration date. Third-party scrapers (maclookup.app) report "11 March 2022" for 98:D9:3D and "December 24, 2024" for 84:49:EE — these are database artifacts, NOT IEEE facts, and must not be displayed as IEEE registration dates.

Parent company
Demant A/S (formerly William Demant Holding A/S), a Danish hearing-healthcare and audio group founded 1904, headquartered in Smørum, DK. Demant sold the EPOS enterprise-audio brand to ACCO Brands across 2024–2025; the OUI registrations predate the divestiture.

Security note
EPOS follows the ETSI EN 303 645 IoT security standard and runs a Security and Compliance Center; DECT and Bluetooth are the primary wireless categories. No CVEs or threat advisories specific to these OUI blocks were found in open sources as of June 2026. (Parent Demant A/S suffered a widely-reported 2019 ransomware incident, but that was enterprise IT, not a device-level OUI issue.)

Analyst note
A globally-administered Demant Enterprise OUI identifies genuine hardware from this legal entity (EPOS-era enterprise audio); but post-2024 these devices may ship under ACCO Brands, so OUI org name and current brand owner can diverge. Don't infer current vendor solely from the registered org.
