Thomas & Betts — 2 prefixes (MA-L)
Summary
- // what this is
- Thomas & Betts is registered to MAC prefix
00:D0:C6and 1 more in the IEEE OUI database. When a device's MAC address begins with00:D0:C6, that block was registered by Thomas & Betts — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Company substance is well-established (founded 1898, long connector-hardware history, verifiable ABB acquisition trail) and its fiber-optic/data-link connector product line plausibly explains company OUI ownership, but no specific networked device model has been tied to either OUI block in this pass — treat the networking tie as category-level, not device-confirmed.
About this vendor.
Thomas & Betts holds two confirmed MA-L (24-bit) OUI blocks registered under two organization-name variants of the same company: 00-D0-C6, registered to "THOMAS & BETTS CORP." at its Australian subsidiary address (Lidcombe, New South Wales), and 60-FE-F9, registered to "Thomas & Betts" at its US headquarters address (5900 Eastport Blvd, Richmond, VA 23231). Founded in 1898 by Robert M. Thomas and Hobart D. Betts, the company built a long history in electrical and communications connector hardware — conduit fittings, crimp and mechanical wire connectors, cable ties (which it invented in 1958), insulation products, and fiber-optic connectors, including "active PCB connector" product lines (e.g. the 92910/92915 series) marketed for data-link applications. ABB Group acquired Thomas & Betts in 2012 for roughly $3.9B and rebranded it ABB Installation Products Ltd. in 2018, while its HVAC subsidiary Reznor was sold off separately to Nortek in 2014. No MA-M or MA-S sub-blocks exist for the company in the cached registries; a third allocation (00:50:C2:CE:80/36) appears only in a third-party Wireshark manuf-file snapshot and could not be confirmed against the current the IEEE MA-S registry, so it is flagged rather than asserted as a company-owned block.
- IEEE assignments
- TWO MA-L blocks — 00-D0-C6 ("THOMAS & BETTS CORP.", Thomas & Betts Aust. Pty. Ltd., Lidcombe, New South Wales, AU) and 60-FE-F9 ("Thomas & Betts", 5900 Eastport Blvd, Richmond, VA, US 23231) [Confirmed] — the IEEE MA-L registry lines 13959, 19523
- Registry / block size
- MA-L (24-bit) only; no MA-M (28-bit) or MA-S (36-bit) block found for Thomas & Betts in the cached registries [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry (searched, no match)
- HQ / country
- US HQ Richmond, VA (60-FE-F9 registry address); Australian subsidiary Lidcombe, NSW (00-D0-C6 registry address) [Confirmed] — IEEE MA-L registry
- Company status
- active as ABB Installation Products Ltd. (rebranded 2018); Thomas & Betts was acquired by ABB Group in 2012 for ~$3.9B [Confirmed] — https://en.wikipedia.org/wiki/Thomas_%26_Betts, https://thomas-and-betts.com/
- Company history
- founded 1898 by Robert M. Thomas and Hobart D. Betts; invented the cable tie in 1958 [Confirmed] — https://en.wikipedia.org/wiki/Thomas_%26_Betts
- Products
- conduit fittings, crimp/mechanical wire connectors, cable ties, insulation products, fiber-optic connectors; Wikipedia describes "networking interconnection systems for voice and data communications" [Confirmed] — https://en.wikipedia.org/wiki/Thomas_%26_Betts, https://thomas-and-betts.com/
- Networking/data-link corroboration
- fiber-optic "active PCB connector" product line (e.g. model 92910/92915 series) marketed for data-link applications — corroborates a plausible reason for company OUI ownership at the product-category level, but no specific networked device model was tied to either OUI in this pass [Likely] — https://www.datasheetarchive.com/thomas%20and%20betts%20FIBER%20OPTIC%20connector-datasheet.html, https://www.ebay.com/p/Thomas-Betts-Cat-No-92910-c5-Fiber-Optic-Active-PCB-Connector-Data-Link-Red/1937012771
- Divestiture note
- HVAC subsidiary Reznor was sold separately to Nortek in 2014, unrelated to the core connector business behind these OUIs [Confirmed] — https://en.wikipedia.org/wiki/Thomas_%26_Betts
- Unconfirmed third block
- Wireshark's the Wireshark manufacturer database file lists 00:50:C2:CE:80/36 "ThomasBetts", but this MA-S block is NOT present in the current the IEEE MA-S registry snapshot and could not be confirmed as a company-owned assignment from the three authoritative registries checked[Unknown] — the Wireshark manufacturer database (non-authoritative third-party file)
- Security context
- no CVEs or vendor security advisories found for Thomas & Betts products in this pass; consistent with a passive electrical/mechanical connector product line rather than IP-networked/software-driven equipment, but treated as "none found" rather than a confirmed absence[Unknown] — (no advisory source found)
- Allocated date
- Unknown/null for both 00-D0-C6 and 60-FE-F9 — IEEE publishes no assignment/registration dates for OUI/MA-L blocks; no date recorded or invented [Confirmed] — n/a (absence of an IEEE field)
- IANA reference
- N/A — not applicable to OUI/MAC vendor entries; left blank
