Cisco SPVTG — 41 prefixes (MA-L)

Cisco SPVTG holds 41 MA-L (24-bit OUI) blocks in the IEEE registry, all registered to 5030 Sugarloaf Parkway, Lawrenceville, GA — the former Scientific-Atlanta headquarters campus that Cisco acquired in February 2006 for roughly $7 billion. "SPVTG" stands for Cisco's Service Provider Video Technology Group, an internal Cisco business unit formed around the Scientific-Atlanta video and set-top-box product lines and later expanded with the DVN set-top-box business (acquired 2009–2010) and NDS (2012). The hardware these blocks identify is overwhelmingly consumer-premise video equipment: cable TV set-top boxes of the Scientific-Atlanta Explorer lineage, DOCSIS cable modem/gateway combos (for example the DPC2320), and smart TVs or satellite receivers that embed a Cisco SPVTG network interface without re-branding it. The practical consequence for anyone scanning a home network: a "Cisco SPVTG" MAC label is almost always a legitimate cable box, gateway, or TV — not an unknown intruder — and the security concern for an identified, owned device is low. One persistent data-quality trap to avoid: third-party MAC-lookup databases display registration and update dates (commonly 2006-06-13 and 2015-11-17) for these blocks, but IEEE publishes no registration dates for MAC/OUI prefixes — those values are database scraper artifacts and must not be recorded as IEEE-sourced facts. The 41 blocks together span roughly 687.9 million assignable addresses, and consolidating them under one vendor entry is far more useful than minting dozens of near-identical per-prefix pages.

IEEE assignment

41 prefixes → Cisco SPVTG, registered Lawrenceville, GA, US [Confirmed] — IEEE MA-L

Registry / block size

MA-L (24-bit OUI); holds 41 IEEE prefixes (~687.9M addresses) [Confirmed] — IEEE the IEEE MA-L registry; maclookup.app, uic.io. NOTE: IEEE's public OUI data publishes NO assignment/registration date; any "date registered" (e.g. 2006-06-13 / 2015-11-17 on maclookup.app) is a database artifact, not an IEEE fact.

HQ / country

5030 Sugarloaf Parkway, Lawrenceville, GA 30044, US (registry address; former Scientific-Atlanta HQ campus) [Confirmed] — IEEE MA-L. One registry entry lists ZIP 30042; one omits the state code.

Registration-date caveat

maclookup.app cites 2006-06-13 (initial) and 2015-11-17 (last update); these are third-party database artifacts, NOT IEEE-published facts, and must not be displayed as IEEE registration dates. [Confirmed as a caveat] — maclookup.app

Analyst note

A Cisco SPVTG OUI on a home-network scan is almost always a legitimate cable box, gateway, or smart TV; security risk for an identified, owned device is low. If unidentified, apply standard network hygiene rather than assuming a SPVTG-specific vulnerability.
