A.N. Solutions GmbH — C4:7D:FE (MA-L)

A.N. Solutions GmbH holds a single MA-L block, C4:7D:FE, registered from Dresden, Germany. Unlike a bare shell registration, the registrant is an identifiable, currently-operating company: an IoT and embedded-systems design house based in Dresden that describes itself as offering hardware design, embedded software, and application development for wireless IoT products. Its stated technical focus is IEEE 802.15.4/Zigbee, 6LoWPAN, and LoRa connectivity, and it markets its own "@ANY" branded component line alongside third-party platforms. The company appears in the German commercial register (HRB 27824, Dresden) and is listed as a design-services provider on DigiKey, which corroborates that the OUI backs real embedded/sensor hardware rather than a placeholder allocation. Two caveats keep this at Medium confidence. First, only one MA-L block exists for the name — no MA-M or MA-S sub-blocks were found, so there is no multi-assignment substance signal. Second, no public product datasheet was found that explicitly ties a specific device model to the C4:7D:FE prefix, so the device-type link is inferred from the company's stated business rather than directly documented. IEEE publishes no assignment date for OUI blocks; any "date registered" shown on third-party MAC-lookup sites is a database artifact and is not recorded here.

IEEE assignment

C4:7D:FE → A.N. Solutions GmbH (MA-L) [Confirmed] — the IEEE MA-L registry line 27260; corroborated by Wireshark the Wireshark manufacturer database snapshot (the Wireshark manufacturer database line 49850, short-name "ANSolutions")

Registry / block size

MA-L (24-bit OUI); single block, ~16.7M addresses [Confirmed] — the IEEE MA-L registry line 27260. No MA-M or MA-S entry for this organization found in the IEEE MA-M registry / the IEEE MA-S registry

Registry address

Am Brauhaus 12, Dresden, Saxony, DE 01099 [Confirmed] — the IEEE MA-L registry line 27260. NOTE: company's current contact page lists Am Brauhaus 5 (same street; minor drift between the registry snapshot and current site, not a red flag)

HQ / country

Dresden, Germany (DE) [Confirmed] — https://an-solutions.de/en/contact.html

Company status

active [Confirmed] — https://an-solutions.de/en/about-us.html; German commercial register HRB 27824, Dresden (https://www.northdata.com/A%C2%B7%20N%C2%B7%20Solutions%20GmbH,%20Dresden/HRB%2027824)

Legal entity

HRB 27824, Amtsgericht Dresden; registered contact Thomas Lerm (direct telephone line not republished here — use the company's published contact page) [Confirmed] — Northdata / Creditreform (https://firmeneintrag.creditreform.de/01099/3070425875/A_N_SOLUTIONS_GMBH)

Device types

embedded / IoT sensor-node and wireless connectivity hardware (IEEE 802.15.4/Zigbee, 6LoWPAN, LoRa); "@ANY" branded modules [Likely] — inferred from https://an-solutions.de/en/about-us.html; no datasheet found publicly citing the C4:7D:FE prefix

Application areas

industrial monitoring/control, smart buildings, smart energy/metering, automotive/transport, smart cities [Likely] — https://an-solutions.de/en/about-us.html (vendor marketing copy)

Third-party corroboration

listed as a DigiKey design-services provider [Confirmed] — https://www.digikey.com/en/design-services-providers/an-solutions-gmbh

Security context

no CVEs, advisories, or abuse/incident reports found for the company [Unknown] — no findable NVD/CISA/CVE entries; absence is not evidence of a clean record

Registration date

none recorded [Confirmed] — IEEE publishes no OUI assignment date; any third-party "date registered" is a database artifact, not an IEEE fact

Analyst note

A globally-administered C4:7D:FE address identifies genuine A.N. Solutions hardware for asset classification; the single-block footprint and absence of a datasheet tying the prefix to a named model mean OUI alone should not be over-read for device-model inventory.
