Ping Communication — 3 prefixes (MA-L)

Ping Communication holds three distinct IEEE MA-L blocks — 78:8C:54, 00:21:94, and 50:4E:DC — all registered to "Ping Communication" at the same address in Appenzell, Switzerland (Brenden 18, Appenzell Meistersrüte). The operating entity behind the name is Ping Communication AS, a Norwegian broadband-CPE maker based in Oslo whose product line runs to VoIP analog telephone adapters (ATAs), integrated access devices combining data/voice/video/wireless with a firewall, and DSL/cable/fiber gateways sold into ISP-provisioned deployments, with a stated concentration in the Latin American market for its fiber-CPE line. The corporate history is well documented: from October 2021 Ping Communication became part of Heimgard Technologies (alongside Home Control and Jensen of Scandinavia), and on 28 March 2025 GX Group announced its acquisition of Ping Communication — the former pingcom.net domain now redirects to gxgroup.eu. Devices bearing these OUIs are therefore ISP-issued gateway/router-class CPE, not enterprise networking gear. One caveat on identification: IEEE publishes no assignment or registration date for any OUI, so no "date registered" appears here; any such value on third-party lookup tools is a database artifact rather than an IEEE fact. The Switzerland registry address and the Oslo operating base coexist in the sources, which is common for a firm that registers its OUIs under one legal-entity address while operating under another.

IEEE assignment

3 prefixes → "Ping Communication", registered Appenzell Meistersrüte, AI, Switzerland (CH 9050) [Confirmed] — IEEE MA-L (:10031, :25828)

Registry / block size

MA-L (24-bit OUI); holds 3 IEEE prefixes [Confirmed] — the IEEE MA-L registry. No MA-M or MA-S (36-bit) blocks exist for this org (only coincidental "ping" substring matches in the IEEE MA-M registry / the IEEE MA-S registry) [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry

Registration date

Unknown — IEEE publishes no OUI assignment/registration date; none present in the cached registry CSV. Not fabricated or backfilled from third-party scrapes. [Confirmed] — IEEE the IEEE MA-L registry columns (Registry, Assignment, Organization Name, Organization Address)

Security context

Unknown — no CVE, default-credential, or vulnerability advisory specifically naming Ping Communication devices found in this pass. Recorded as a sourced null, not "secure" or "vulnerable." [Unknown]

Analyst note

A globally-administered Ping Communication OUI reliably identifies genuine Ping/Heimgard/GX-lineage broadband CPE for asset classification; the operating-company identity (Norwegian Ping Communication AS) is well corroborated, while the Switzerland registry address is the IEEE-of-record address for the three blocks.
