CommScope / ARRIS — ~345+ prefixes across many entities (MA-L + MA-S); broadband CPE, OUI = brand + ISP-supplied

CommScope's MAC footprint is one of the largest in the project and spans many IEEE registrants that should be aliased to one family: "Commscope" (~345 blocks) plus legacy "Arris", "ARRIS Group, Inc.", and the Motorola Home / General Instrument / Pace lineage. Both MA-L and MA-S blocks appear. The registered address 6450 Sequence Drive, San Diego, California is used by both CommScope and ARRIS Group blocks; the corporate HQ is Hickory, North Carolina. Verified samples include 18:35:D1 (Commscope), 34:2B:70 and the MA-S sub-block 70:B3:D5:98:8/36 (Arris), F8:79:0A (ARRIS Group), and the legacy 00:00:CA (Arris/General Instrument). These OUIs appear on cable modems, residential gateways, set-top boxes, CMTS, Wi-Fi systems, and the SURFboard retail modem line. The lineage is layered: CommScope acquired ARRIS (completed 2019-04-04, ~$7.4B); ARRIS had earlier acquired Motorola Mobility's home unit / General Instrument from Google (completed 2013-04-17, $2.35B) and Pace plc (completed 2016-01-04, ~£1.4B/$2.1B). Most gear is ISP-supplied CPE, with SURFboard the main retail exception; CommScope also owns Ruckus (covered separately — note the relationship but keep Ruckus distinct). For triage, a CommScope/ARRIS/Motorola/GI/Pace OUI almost always flags broadband CPE — a cable modem, gateway, or set-top box; most are ISP-deployed, while a SURFboard MAC indicates retail-purchased gear, and all the legacy names should be treated as one vendor family.

IEEE assignment

many entities — "Commscope" (~345) + legacy "Arris", "ARRIS Group, Inc.", Motorola Home / General Instrument / Pace [Confirmed] — IEEE MA-L/MA-S

Registry / block size

Company status

active; CommScope acquired ARRIS (completed 2019-04-04, ~$7.4B); ARRIS acquired Motorola Home/General Instrument from Google (completed 2013-04-17, $2.35B) and Pace plc (completed 2016-01-04, ~£1.4B/$2.1B); CommScope acquired Andrew (2007) [Confirmed] — ARRIS SEC Form 8-K, corporate

Device types

cable modems, residential gateways, set-top boxes, CMTS, Wi-Fi systems, SURFboard retail modems [Confirmed] — maclookup.app

Notable products

SURFboard cable modems (retail), DOCSIS gateways, set-top boxes (Motorola/GI lineage), E6000 CMTS

Verified prefix sample

18:35:D1 (Commscope); 34:2B:70 + 70:B3:D5:98:8/36 (MA-S sub-block) (Arris); F8:79:0A (ARRIS Group); 00:00:CA (legacy Arris/General Instrument) [Confirmed] — maclookup.app

Special note

Big multi-OUI vendor — consolidate ARRIS, Arris Group, Motorola Home, General Instrument, and Pace under CommScope. Most gear is ISP-supplied CPE (carrier-branded, like Calix/Adtran/DZS), but SURFboard is retail. CommScope also owns Ruckus (covered separately — keep distinct). 70:B3:D5 is a shared IEEE MA-S base range (the IEEE Registration Authority is its MA-L holder); only the assigned /36 sub-block 70:B3:D5:98:8 belongs to Arris/CommScope, not the whole base OUI. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]

Related vendors

Ruckus (CommScope subsidiary); legacy Motorola Home, General Instrument, Pace, Andrew

Analyst note

A CommScope/ARRIS/Motorola/GI/Pace OUI almost always flags broadband CPE — a cable modem, gateway, or set-top box; most are ISP-deployed, a SURFboard MAC indicates retail gear, and all the legacy names are one vendor family.
