MaxLinear — 5 prefixes (MA-L, 2 registrant entities)

MaxLinear, Inc. (Nasdaq: MXL) is a publicly traded, fabless analog/mixed-signal semiconductor company founded in 2003 and headquartered in Carlsbad, California, with international design offices in Israel, Germany, and Spain. The local IEEE registry cache shows five distinct MA-L (24-bit) OUI blocks tied to the MaxLinear corporate family, split across two registrant strings: "Maxlinear, Inc" / "Maxlinear Inc" (US and international addresses) and "MaxLinear Hispania S.L.U." (a Spain-based entity, Paterna). This is a real chipset vendor rather than a bare registration — MaxLinear silicon ships in DOCSIS 3.0/3.1 cable-modem SoCs, DSL/G.hn gateway chipsets, Wi-Fi 6/6E/7 access-point and gateway SoCs, and Ethernet PHY/switch interface ICs, all consumer/carrier network-facing gear where its OUIs would plausibly appear on device MAC addresses. Whether the "vendor-maxlinear" slug is meant to consolidate all five blocks under one entry or split by legal entity is an open question this batch item does not resolve; the JSON below records all five as one family for producer/checker disambiguation.

IEEE assignment 00-50-F1

Maxlinear, Inc, Petach-Tikva, Israel [Confirmed] — the IEEE MA-L registry

IEEE assignment F0-4C-D5

Maxlinear, Inc, Carlsbad, CA, US [Confirmed] — the IEEE MA-L registry

IEEE assignment 0C-4E-C0

Maxlinear Inc, San Jose, CA, US [Confirmed] — the IEEE MA-L registry

IEEE assignment AC-9A-96

Maxlinear, Inc, Neubiberg, Bavaria, DE [Confirmed] — the IEEE MA-L registry

IEEE assignment 00-13-9D

Registry / block size

MA-L (24-bit OUI) for all five blocks; no MA-M/MA-S block appears for MaxLinear in the primary the IEEE MA-S registry cache [Confirmed] — the IEEE MA-S registry (absence checked)

Unconfirmed secondary-source block

00:50:C2:12:60/36 → MaxLinear Hispania, listed only in the secondary Wireshark-derived the Wireshark manufacturer database cache, not present in the primary the IEEE MA-S registry MA-S registry [Unknown] — the Wireshark manufacturer database

Assignment/registration dates

none recorded. IEEE's public OUI data publishes no assignment date; third-party "date registered" values are database artifacts, not IEEE facts, and none was reliably retrieved for this vendor anyway (adminsub.net returned HTTP 522 during the web pass)

[Confirmed — absence] — no citation (negative finding)

Device / product context

DOCSIS 3.0/3.1 cable-modem SoCs, DSL/G.hn gateway chipsets (e.g. 88LX5152+88LX2720, selected by Comtrend), Wi-Fi 6/6E/7 AP/gateway SoCs (WAV600 series), Ethernet PHY/interface ICs (e.g. GPY212) [Confirmed] — https://www.comtrend.com/News/232$prod.html, https://www.maxlinear.com/wi-fi, https://www.maxlinear.com/product/interface/ethernet/ethernet-transceivers-phy/gpy212, https://www.maxlinear.com/news/press-releases/2022/maxlinear-boosts-its-gateway-access-platform-with

Security context

no MaxLinear-specific CVEs or chipset advisories found in a light pass; general DOCSIS-modem vulnerability research (e.g. Cable Haunt) named Broadcom-based modems specifically, not MaxLinear — treat as unknown/no-adverse-finding rather than clean, since this was not an exhaustive CVE-database query

Entity relationship

MaxLinear Hispania S.L.U. (Spain, 00-13-9D) appears to be a distinct legal entity from the US-registered Maxlinear, Inc / Maxlinear Inc (the other four blocks); org-name strings are copied verbatim from the registry, not merged/normalized [Likely] — the IEEE MA-L registry

Company substance verdict

substantive — identifiable public company with a documented product line and 5 distinct OUI assignments across geographically distinct registrant addresses, not a single-OUI shell registration [Confirmed] — the IEEE MA-L registry, https://www.maxlinear.com/
