MAC address vendor

Proxim Wireless — 2 prefixes (MA-L)

Primary prefix
00:20:A6
Block
MA-L
Status
Active

Summary

// what this is
Proxim Wireless is registered to MAC prefix 00:20:A6 and 1 more in the IEEE OUI database. When a device's MAC address begins with 00:20:A6, that block was registered by Proxim Wireless — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Both 00:20:A6 and 04:F5:F4 are full, unshared MA-L blocks registered solely to Proxim Wireless, so a MAC in either range attributes directly to the company; check device context to distinguish the ORiNOCO Wi-Fi line from the Tsunami backhaul line rather than assuming one product family from the OUI alone.

About this vendor.

Updated  ·  Confidence: High  ·  9 sources  ·  How this page is checked

A MAC address beginning 00:20:A6 or 04:F5:F4 identifies hardware built by Proxim Wireless, a San Jose, California maker of point-to-point and point-to-multipoint wireless backhaul radios and outdoor Wi-Fi access points. Both blocks are full MA-L (/24) assignments registered to the same company at the same address, which is itself a signal of an established vendor rather than a shell registrant.

Proxim's roots trace to Proxim Corporation, founded in 1984 in Mountain View, CA, an early WLAN pioneer (RangeLAN, 2.4GHz WLAN cards) that acquired Western Multiplex and Agere's ORiNOCO wireless line in 2002. The company filed Chapter 11 in June 2005 and was acquired by Terabeam Inc. that year; Terabeam renamed itself Proxim Wireless Corporation in September 2007.

As of an August 2026 check, proxim.com is live, headquartered in San Jose, and brands itself "AN SRA COMPANY" — a different parent than the Terabeam lineage described on Wikipedia, so a later ownership change may not be reflected there; both accounts are cited separately rather than reconciled.

Current products span four lines per the company's own site: point-to-point backhaul radios, point-to-multipoint aggregation radios, outdoor Wi-Fi access points, and network planning/management tools. Named families include ORiNOCO (Wi-Fi access points, e.g. the AP-9200R) and Tsunami (microwave backhaul, e.g. the MP.11 2411).

Two device-specific CVEs are recorded in the NVD as of an August 2026 search, both against Tsunami MP.11 2411 firmware 3.0.3: a default SNMP read/write community string of "public" (CVE-2008-5866, CVSSv2 10.0) and a reflected XSS via the sysName SNMP OID (CVE-2008-5869, CVSSv2 4.3). No CVE naming the ORiNOCO Wi-Fi line is recorded as of the same search.
