Scientific-Atlanta, Inc. — 8 MA-L prefixes (consolidated vendor)

Scientific-Atlanta was a cable-television and broadband equipment maker headquartered at 5030 Sugarloaf Parkway, Lawrenceville, Georgia, founded in October 1951 by six Georgia Tech Research Institute engineers. Its product line centered on residential and headend cable gear: the Explorer series of digital set-top boxes, cable modems such as the DPX2100 and the D20/D30-based line, and — after a 1997 acquisition of the Danish firm Arcodan A/S — headend and RF distribution equipment. Cisco Systems acquired Scientific-Atlanta on November 18, 2005 (deal closed February 25, 2006) for roughly $6.9 billion, at the time Cisco's largest acquisition; Cisco later sold the former Scientific-Atlanta Connected Devices Business Unit, including its set-top and gateway line, to Technicolor SA on November 21, 2015. The local IEEE MA-L registry cache shows eight blocks registered under Scientific-Atlanta name variants, all tied to the Lawrenceville (or Norcross) Georgia address, plus one additional block registered separately to "Scientific-Atlanta Arcodan A/S" at a Danish address — a distinct legal entity from the Arcodan acquisition, flagged here rather than silently folded into the core count. A confirmed device-level vulnerability (CVE-2012-3047, per official Cisco Security Advisory) further corroborates that these OUIs identify real, deployed cable-CPE hardware rather than a bare unused registration.

IEEE assignment

Subsidiary block (flagged, not folded into core count)

00:01:A6 → "Scientific-Atlanta Arcodan A/S", Avgustenborg Landevej 7, Denmark — a distinct legal entity acquired by Scientific-Atlanta in February 1997 (Arcodan A/S, Danish maker of cable headend/opto-electronics/RF distribution gear, ~270 employees, Sønderborg DK); corroborated independently by contemporaneous wire coverage and the company's FY1997 SEC 10-K [Confirmed] — the IEEE MA-L registry (line 21760), https://www.upi.com/Archives/1997/02/19/Scientific-Atlanta-buys-Arcodan/8893856328400/, https://www.sec.gov/Archives/edgar/data/0000087777/000093176397001578/0000931763-97-001578.txt

Security context

CVE-2012-3047 (Cisco Security Advisory, published 2012-06-13) — cross-site-scripting vulnerability in the web setup wizard of Scientific Atlanta D20 and D30-based cable modems, exploitable by an unauthenticated remote attacker

[Confirmed] — https://www.cisco.com/c/en/us/support/docs/csa/Cisco-SA-20120613-CVE-2012-3047.html

Date registered

Unknown — IEEE publishes no assignment/registration dates for MA-L OUI blocks, and the cached the IEEE MA-L registry schema (registry_class, oui_hex, org, address) has no date column; not fabricated or inferred

[Confirmed] — the IEEE MA-L registry, https://standards.ieee.org/products-programs/regauth/mac/

IANA reference

not applicable / blank — OUI/MAC vendor registrations are an IEEE Registration Authority matter, not an IANA one [Confirmed]

Related vendors

Cisco Systems (acquirer, 2005/2006), Technicolor SA (acquired the CPE line, 2015), Arcodan A/S (Danish subsidiary, acquired 1997; separate OUI block 00:01:A6)

Analyst note

eight MA-L blocks under the core GA org-name variants plus one separately-registered Danish subsidiary block establish this as a large, well-corroborated legacy cable-equipment vendor, not a thin single-block registrant — appropriate to consolidate into one vendor page.
