Xirrus, Inc. — 3 prefixes (MA-L)

A MAC address beginning 00:0F:7D, 48:C0:93, or 50:60:28 belongs to Xirrus, Inc., typically seen on enterprise Wi-Fi access points and "Wi-Fi Array" multi-radio hardware built for large-venue wireless deployments such as campuses, stadiums, and large offices rather than consumer gear.

Xirrus was founded in 2004 and based first in Westlake Village, California, then Thousand Oaks, California — the move is visible in the registry, where its oldest OUI (00:0F:7D) carries the Westlake Village address and its two newer blocks (48:C0:93, 50:60:28) carry Thousand Oaks. Riverbed Technology acquired Xirrus in April 2017, folding it into Riverbed's SD-WAN line; Riverbed then sold the Xirrus Wi-Fi business to Cambium Networks in August 2019, where the product line continues today.

Xirrus hardware shipped under the Wi-Fi AOS, Wi-Fi AOSLite, and Wi-Fi AOS FIPS operating systems, across catalogued models such as the XR-620, XR-630, XD4-130, X2-120, and XR-320 — Cambium Networks, the current owner, still names these models in its own security advisories for the legacy Xirrus line, which is strong corroboration that these OUIs map to real, supported enterprise access points rather than a bare registration.

Two sourced security items exist for the vendor's own products: CVE-2017-6557, a SQL injection in Xirrus ArrayOS before 9.4.0.135 (CVSSv3 8.8), and the 2021 "FragAttacks" family of 802.11 frame-aggregation flaws, which affected many vendors' implementations and were confirmed present on Xirrus Wi-Fi AOS/AOSLite/AOS-FIPS access points per Cambium's advisory.

Prefixes

00:0F:7D, 48:C0:93, 50:60:28 — three direct MA-L (/24) assignments

Registrant

Xirrus / Xirrus, Inc. / Xirrus Inc. (name and address formatting differs by assignment)

Company status

Acquired — Riverbed Technology (2017), then Cambium Networks (2019); product line active under Cambium

Also seen on

catalogued models named in a current Cambium Networks security advisory, including XR-620, XR-630, XD4-130, X2-120, and XR-320

Security history

CVE-2017-6557 (SQL injection, ArrayOS); FragAttacks-era 802.11 CVEs affecting Wi-Fi AOS/AOSLite/AOS-FIPS hardware

Shared-base status

None of these prefixes is a shared IEEE Registration Authority base — all three are direct assignments to Xirrus, so no sub-allocation caveat applies

IEEE assignment

3 MA-L prefixes → Xirrus / Xirrus, Inc. (name/address varies by block), registered Westlake Village, CA and Thousand Oaks, CA, US [Confirmed] — the IEEE MA-L registry (rows 000F7D, 48C093, 506028)

Registry / block size

MA-L (24-bit OUI); 3 IEEE prefixes found; no MA-M or MA-S sub-blocks located for Xirrus [Confirmed] — the IEEE MA-L registry, the IEEE MA-S registry, the IEEE MA-M registry. NOTE: these registry rows carry no assignment-date field; IEEE's public OUI data publishes no registration dates.

HQ / country

2101 Corporate Center Dr, Thousand Oaks, CA 91320, US (current registry address, two of three blocks); 310 North Westlake Blvd, Westlake Village, CA 91362, US (registry address on the oldest block, 00:0F:7D) [Confirmed] — the IEEE MA-L registry

Company status

Acquired by Riverbed Technology (April 2017), then sold by Riverbed to Cambium Networks (August 2019), where the Wi-Fi line continues [Confirmed] — businesswire.com, globenewswire.com

Device types

enterprise / high-density Wi-Fi access points, "Wi-Fi Array" multi-radio units for large-venue deployments [Confirmed] — networkworld.com, cambiumnetworks.com

Notable products

Wi-Fi Array (integrated radios, sectored directional antennas, multi-gigabit switch, controller, firewall, spectrum analyzer in one chassis); Wi-Fi AOS / AOSLite / AOS FIPS; named models incl. XR-620, XR-630, XD4-130, X2-120, XR-320 [Confirmed] — cambiumnetworks.com (security advisory 2021-02)

Verified sample prefixes (all MA-L)

00:0F:7D, 48:C0:93, 50:60:28 [Confirmed] — the IEEE MA-L registry

Special note

All three blocks are direct MA-L assignments to Xirrus, not sub-allocated from a shared IEEE Registration Authority base — no shared-base ownership caveat applies to these prefixes [Confirmed] — the IEEE MA-L registry

Related vendors

Cambium Networks (current owner of the Xirrus Wi-Fi line, since 2019); Riverbed Technology (previous owner, 2017-2019) [Confirmed] — globenewswire.com

Analyst note

Three separate OUI assignments, a documented acquisition trail (Riverbed 2017 to Cambium Networks 2019), named product/OS lines, and a vendor-specific CVE together indicate genuine catalogued enterprise hardware rather than a shell registration
