Linksys's MAC footprint is dominated by the historic "Cisco-Linksys, LLC" registrant (25 MA-L blocks), with newer blocks appearing under "Linksys" / "Belkin International" — all of which should be aliased to one brand. The Cisco-Linksys blocks are registered at 121 Theory Dr., Irvine, CA (older blocks list 170 W Tasman Dr, San Jose). These OUIs appear on consumer/SOHO routers, Wi-Fi mesh systems (Velop), wireless access points, switches, and range extenders. The corporate history matters for normalization: Linksys was founded in 1988, acquired by Cisco in 2003 (becoming Cisco-Linksys), sold to Belkin in 2013, and then — together with Belkin — acquired by Foxconn in 2018, so it now operates under a Belkin/Foxconn structure. Importantly, the "Cisco-Linksys" string predates the Belkin/Foxconn ownership and should NOT be conflated with enterprise Cisco gear (the standalone Cisco entry covers that). For triage, a Cisco-Linksys OUI almost always indicates a consumer/SOHO router or AP — in an enterprise context, a likely shadow-IT / rogue-AP signal.

- Special note
- Dominant registrant is "Cisco-Linksys, LLC" (the string predates Belkin/Foxconn ownership) — do NOT conflate with enterprise Cisco gear; newer blocks under "Linksys"/"Belkin International." Alias all to one brand. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed] — maclookup.app/vendors/cisco-linksys-llc
