Ericsson Group — 2 prefixes (MA-L); legacy Telefonaktiebolaget LM Ericsson registration

A MAC address starting with 00:80:37 or 00:01:EC belongs to "Ericsson Group," an IEEE MA-L registrant tied to Telefonaktiebolaget LM Ericsson, the Swedish telecommunications-equipment manufacturer better known simply as Ericsson. This is a corporate-level legal-parent registration, not a product-line registration.

Only two MA-L blocks carry this exact registrant string, and the registry row for both is sparse: it lists just "Telefonaktiebolaget" and country code SE, with no street address, city, or postal code — unlike the fuller "Torshamnsgatan 36, Stockholm" address used on Ericsson's later, more numerous "Ericsson AB" blocks.

Ericsson itself is a substantial, well-documented company: publicly traded (Nasdaq Stockholm: ERIC B), and the IEEE OUI registry carries roughly 40+ rows across at least eight distinct Ericsson-related registrant strings (Ericsson AB, Ericsson Group, Ericsson, Ericsson Television Limited, Ericsson - North America, Ericsson-LG Enterprise, LG-Ericsson Co.,Ltd., and Ericsson, EAB/RWI/K), so this is not a bare single-OUI shell.

Device-class attribution is unconfirmed for these two specific blocks. No source ties 00:80:37 or 00:01:EC to a named product line; Ericsson's broader product domain (carrier RAN, transport, and core network equipment) is established for the separately-verified "Ericsson AB" registrant, but that context does not automatically carry over to this distinct legacy registration.

"Ericsson Group" must not be conflated with two other Ericsson-branded registrants in the same registry: "Ericsson AB" (the primary, ~28-block registrant, already a DONE entry) and "Ericsson, EAB/RWI/K" (a regional unit-code registrant, still queued and unresearched). Each is a separate legal registrant string with its own prefix set.

IEEE assignment

2 prefixes (00:80:37, 00:01:EC) → "Ericsson Group", registered SE (Sweden) [Confirmed] — the IEEE MA-L registry 008037, the IEEE MA-L registry 0001EC

Registry / block size

MA-L (24-bit OUI); 2 IEEE prefixes under this exact registrant string, verified by full-text grep of the registry [Confirmed] — the IEEE MA-L registry

HQ / country

"Telefonaktiebolaget SE" — abbreviated legal-parent name only, no street/city/postal code present in either registry row; country SE (Sweden) [Confirmed] — the IEEE MA-L registry 008037, the IEEE MA-L registry 0001EC

Company status

active; legal parent Telefonaktiebolaget LM Ericsson (Ericsson), publicly traded (Nasdaq Stockholm: ERIC B) [Confirmed] — https://www.ericsson.com

Device types

Verified sample prefixes (both MA-L, "Ericsson Group")

00:80:37, 00:01:EC [Confirmed] — the IEEE MA-L registry 008037, the IEEE MA-L registry 0001EC

Registration date

Unknown — IEEE the IEEE MA-L registry publishes no assignment/registration date for MAC prefixes; not stated here. A third-party tool shows scrape dates (22 Apr 1998 for 008037; 9 Nov 2000 for 0001EC) that are database artifacts, not IEEE facts

[Confirmed absence of IEEE date] — the IEEE MA-L registry

Special note

"Ericsson Group" is a distinct IEEE registrant string from "Ericsson AB" (vendor-ericsson, DONE, ~28 blocks, Torshamnsgatan 36 Stockholm) and "Ericsson, EAB/RWI/K" (vendor-ericsson-eabrwik, queued/unresearched) — do not merge prefix lists across these entries [Confirmed] — the IEEE MA-L registry

Related vendors

Ericsson AB (vendor-ericsson, parent/primary registrant string, DONE); Ericsson, EAB/RWI/K (vendor-ericsson-eabrwik, queued); Cradlepoint (Ericsson subsidiary since 2020-11-02, separate OUIs) [Confirmed] — /mac/vendor/ericsson/

Analyst note

A 00:80:37 or 00:01:EC prefix identifies the Ericsson corporate registrant (legal parent Telefonaktiebolaget LM Ericsson) but does not by itself confirm a device class for these two blocks; don't assume carrier-RAN hardware from this registrant string alone without corroboration [Confirmed reasoning; Unknown device mapping] — the IEEE MA-L registry, /mac/vendor/ericsson/
