Power Plus Communications AG — smart meter gateway prefixes (MA-L)

Power Plus Communications AG (PPC) is a German smart-metering technology company headquartered in Mannheim, and a MAC address beginning with one of its IEEE-assigned OUI prefixes typically belongs to a Smart Meter Gateway (SMGW) or a broadband-powerline (BPL) / cellular (LTE, LTE450) communication module built for German and EU energy-metering infrastructure.

Founded in 2001, PPC builds the hardware and firmware that links utility smart meters to grid operators and energy suppliers. Its flagship Ethernet Smart Meter Gateway carries a BSI Common Criteria certification (protection profile BSI-CC-PP-0073) plus PTB type-examination approval (PTB-A 50), and is built to Germany's TR-03109 and FNN technical guidelines — a level of formal security certification well beyond a typical bare single-OUI shell registration.

The cached IEEE OUI registry (the IEEE MA-L registry) lists three MA-L prefixes under this registrant: 0C:EB:25 and 3C:08:68 are registered to "Power Plus Communications AG", Dudenstrasse 6, Mannheim, DE 68167; 00:25:18 is registered to the older spelling "Power PLUS Communications AG", Am Exerzierplatz 2, Mannheim, Baden Wuerttemberg, DE 68167 — the registry itself is inconsistent in capitalisation between the two records. maclookup.app independently lists the same three prefixes under the company, and api.macvendors.com corroborates 3C:08:68.

Any "registered" date shown by third-party lookup tools for these prefixes is a database artifact, not an IEEE-published fact — IEEE's own OUI data carries no assignment-date field.

IEEE assignment

3 prefixes (00:25:18, 0C:EB:25, 3C:08:68) [Confirmed] — the IEEE MA-L registry lines 20313 ("Power PLUS Communications AG", Am Exerzierplatz 2, Mannheim), 7511 and 30496 ("Power Plus Communications AG", Dudenstrasse 6, Mannheim); corroborated by maclookup.app

Verified sample prefixes

00:25:18, 0C:EB:25, 3C:08:68 [Confirmed] — the IEEE MA-L registry; 3C:08:68 further cross-confirmed by a second independent source — api.macvendors.com

Special note

Third-party "registered" dates for these prefixes (e.g. 00:25:18 shown as 2009-02-02 on maclookup.app) are database artifacts, not IEEE-published facts; IEEE's the IEEE MA-L registry carries no assignment-date field. [Confirmed] — IEEE the IEEE MA-L registry format / project rule

Related vendors

confirmed blank — no subsidiary/parent relationship found in the IEEE MA-L registry or ppc-ag.de [Confirmed]

Analyst note

All three prefixes are confirmed first-party in the cached IEEE registry under "Power Plus Communications AG" (and the older "Power PLUS Communications AG" spelling for 00:25:18), matching the company's Mannheim HQ and product line. [Confirmed]
