MSC Vertriebs GmbH — 2 prefixes (MA-L)
Summary
- // what this is
- MSC Vertriebs is registered to MAC prefix
00:03:05and 1 more in the IEEE OUI database. When a device's MAC address begins with00:03:05, that block was registered by MSC Vertriebs — the OUI identifies the maker of the network hardware, which is not always the brand on the device. MSC Vertriebs was acquired; the registration remains on record with IEEE. - // analyst note
- Legitimate embedded-computing hardware vendor with substantive documented history predating and following its 2013/2014 acquisition by Avnet; holds two full OUI blocks in its own name, not shared-base sub-allocations. No malware/CVE association found; the sole 'MSC'-adjacent security hit (CVE-2025-26633 'MSC EvilTwin') concerns unrelated Windows .msc console files.
About this vendor.
A MAC address beginning with 00:03:05 or 00:30:D6 belongs to MSC Vertriebs GmbH, a German embedded-computing hardware manufacturer, and typically appears on industrial computer-on-module or I/O-expansion boards the company shipped.
MSC Vertriebs GmbH was a Stutensee, Germany-based distributor and manufacturer founded in 1982, with a Design Center in Aachen. Its product line centered on embedded computing: COM Express and ETX computer-on-modules, Qseven modules, the FeaturePak/EXM-32 I/O-expansion family, industrial motherboards, and evaluation carrier boards such as the MSC C6-MB-EVA.
Avnet Inc. acquired the company in a two-step deal — a majority stake on October 1, 2013, and the remaining interest completed by January 31, 2014 — after which it was rebranded MSC Technologies, an Avnet Company, now folded into Avnet Embedded. This acquisition history, combined with holding two separate OUI blocks and a documented product line, distinguishes the entry from a bare single-OUI registration.
IEEE's MA-L registry lists both 00:03:05 and 00:30:D6 as full MA-L assignments registered directly to this company — neither is a sub-allocation of a shared IEEE Registration Authority base. IEEE does not publish assignment dates; a "registered 2000-11-09" date shown by third-party lookup sites is a database artifact of the aggregator, not an IEEE fact.
No CVE, malware family, or botnet association is recorded for MSC Vertriebs GmbH or these OUI blocks as of an August 2026 search. The only "MSC"-adjacent security hit, CVE-2025-26633 ("MSC EvilTwin"), concerns malicious Windows .msc console files exploited by unrelated threat actors and does not connect to this vendor.

- IEEE MA-L registry publishes no assignment date; third-party sites (maclookup.app, rst.im) show a "registered 2000-11-09 / updated 2015-11-17" date for both prefixes, which is a database artifact of the aggregator, not an IEEE fact [Confirmed] — maclookup.app
- Security note
- no CVE, malware, or botnet association recorded for this vendor or its OUI blocks as of an August 2026 search; CVE-2025-26633 ("MSC EvilTwin") is a same-name coincidence involving Windows .msc console files, unrelated to this vendor [Confirmed] — thehackernews.com, trendmicro.com
