MAC address vendor

Octagon Systems Corp. — 2 prefixes (MA-L)

Primary prefix
FC:95:6A
Block
MA-L

Summary

// what this is
Octagon Systems is registered to MAC prefix FC:95:6A and 1 more in the IEEE OUI database. When a device's MAC address begins with FC:95:6A, that block was registered by Octagon Systems — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
A MAC beginning FC:95:6A or 00:20:0B identifies genuine Octagon/TRAX embedded hardware. These are rugged/embedded devices, so consumer-style MAC randomization is not a classification concern.

About this vendor.

Updated  ·  Confidence: Medium

Octagon Systems is an industrial and embedded computing manufacturer founded in 1981 in Westminster, Colorado, and it holds two IEEE MA-L blocks — FC:95:6A and 00:20:0B — both registered to "OCTAGON SYSTEMS CORP." at 7403 Church Ranch Blvd, Westminster, CO 80021, US. The company built single-board computers for the STD Bus market, helped shape the EPIC embedded form-factor spec, and shipped MIL-SPEC "rugged"/"Octagon Tough" conduction-cooled computers for mining, transportation, and defense customers, including U.S. Navy amphibious-warfare computing. In 2018 J-Squared Technologies acquired the Octagon and TRAX product line; the Westminster manufacturing facility was closed, but the Octagon Systems brand and the TRAX family of rugged computers are still sold today under J-Squared. Consistent with that history, octagonsystems.com now 301-redirects to jsquared.com/products, confirming the brand is live under new ownership. Because two independent OUI blocks share the same registrant name and address and the company itself is documentable with a real, specific product line, this is a substantive multi-OUI vendor rather than a bare single-prefix shell. A MAC that begins with FC:95:6A or 00:20:0B therefore reliably points to genuine Octagon/TRAX embedded hardware; note that the second block, 00:20:0B, sits in the low-numbered early OUI range consistent with a long-established 1980s-era vendor, though IEEE publishes no assignment date to confirm exact timing.

IEEE assignment
2 prefixes → OCTAGON SYSTEMS CORP., registered Westminster, CO, US [Confirmed] — IEEE MA-L (:37856)
Registry / block size
MA-L (24-bit OUI); holds 2 IEEE prefixes [Confirmed] — the IEEE MA-L registry. NOTE: IEEE's public OUI data publishes NO assignment/registration date (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address); a third-party claim that FC:95:6A was "registered 12 February 2020" is a database artifact, NOT an IEEE fact, and is not recorded here.
HQ / country
7403 Church Ranch Blvd, Westminster, CO 80021, US (IEEE registry address; manufacturing site closed after 2018 J-Squared acquisition) [Confirmed] — IEEE MA-L
Company status
brand active under J-Squared Technologies (acquired Octagon/TRAX line 2018); original Westminster facility closed [Likely] — en.wikipedia.org/wiki/Octagon_Systems, jsquared.com/manufacturers/octagon-systems, octagonsystems.com (301 → jsquared.com/products)
Device types
single-board computers (STD Bus, EPIC form factor), industrial/rugged PCs, TRAX conduction-cooled MIL-SPEC rugged computers [Confirmed] — en.wikipedia.org/wiki/Octagon_Systems, jsquared.com/products/small-form-factor-computers/traxtm
Notable products
TRAX rugged computer family; EPIC embedded computing spec; "Octagon Tough" rugged line
Verified sample prefixes (both MA-L, OCTAGON SYSTEMS CORP.)

Industry / market
industrial, embedded, and rugged/MIL-SPEC computing (mining, transportation, defense, IoT/V2X) [Confirmed] — en.wikipedia.org/wiki/Octagon_Systems
Security / abuse context
Unknown / no findings. No CVE, CISA KEV, or abuse reporting was found naming Octagon Systems hardware or its OUI prefixes. Recorded as a sourced null (consistent with a low-volume legacy industrial vendor), NOT overclaimed as "clean." [Likely] — NVD/CISA/CVE search returned no relevant hits
False positives excluded
address-only "octagon" string matches (Nextek Solutions Pte Ltd F0:F0:8F "The Octagon Singapore"; Cosworth Electronics Ltd 00:E0:B7 "The Octagon, St. James Mill Road") are unrelated companies and are NOT attributed to this vendor [Confirmed] — the IEEE MA-L registry
Analyst note
A MAC beginning FC:95:6A or 00:20:0B identifies genuine Octagon/TRAX embedded hardware. Because these are rugged/embedded devices (not consumer Wi-Fi), MAC randomization is not a concern for asset classification the way it is for phones/laptops.
