A. S. Thomas, Inc. — 08:18:4C (MA-L)

A MAC address beginning 08:18:4C is registered to A. S. Thomas, Inc., a precision-manufacturing company headquartered in Westwood, Massachusetts. No networked-hardware product carrying this prefix has been identified from any source checked, so the vendor is confirmed but the specific device class is Unknown rather than inferred.

A. S. Thomas is a real, long-operating business, not a bare shell registration: company materials describe a CNC machine shop founded in 1955 doing 3/4/5-axis precision machining, with its own named product lines — NUFORM CAM software, and ASTRRA and Scroll-EX systems built for packaging-industry timing-screw work. It maintains an active company website and LinkedIn page, and appears in standard business-data-broker listings.

That substance is company-level, not network-level. The company's own site describes CAM software and precision-machined mechanical/packaging components, with no stated network interface or embedded controller product. A search of the OUI registries turned up only this single MA-L block under the company's name — no MA-M or MA-S sub-allocations — so the case for substance rests on the business being real and findable, not on multiple OUI holdings.

A third-party lookup tool lists a "registered" date of 05 January 2010 with an update of 17 November 2015 for this prefix. That is a database artifact from the tool's own records, not an IEEE-published fact — IEEE's public OUI data carries no assignment or registration date field at all.

Verified sample prefix

08:18:4C (sole known block for this company) [Confirmed] — the IEEE MA-L registry 08184C

Registration date caveat

maclookup.app lists "initially registered 05 January 2010", updated 17 November 2015 — a third-party database artifact, not an IEEE-published fact; IEEE's the IEEE MA-L registry publishes no assignment/registration date [Confirmed] — https://maclookup.app/macaddress/08184c

Company substance

founded 1955, active CNC precision-manufacturing business with named software/product lines and a public web/LinkedIn presence — sufficient to distinguish this from a bare single-OUI shell registration, even though device-network context is unconfirmed [Likely] — https://asthomas.com/about/, https://rocketreach.co/a-s-thomas-inc-profile_b5c1b4fbf42e08d6, https://www.zoominfo.com/c/a-s-thomas-inc/7885014

Analyst note

08:18:4C is an exclusively-held MA-L block, not a shared IEEE base, so a device presenting this prefix is genuinely A. S. Thomas hardware; but since no networked product has been publicly identified for the company, do not infer a device class (e.g. "industrial control") beyond what its own manufacturing/CAM-software business describes
