Select Comfort (Sleep Number) — 2 prefixes (MA-L)

Select Comfort holds two MA-L (24-bit) OUI blocks — 64-DB-A0 and CC-04-B4 — both registered to the same Minneapolis, MN headquarters address (9800 59th Ave N, Minneapolis, MN 55442, US) in the cached IEEE registry mirror. Select Comfort Corporation is a publicly traded Minneapolis bedding manufacturer, founded 1987, best known for its SLEEP NUMBER adjustable air-bed line; the company renamed itself Sleep Number Corporation in 2017, keeping the SLEEP NUMBER brand for its flagship product. Independent third-party MAC-vendor lookup sites and a Ubiquiti community forum thread both associate these two prefixes with Sleep Number's WiFi/Bluetooth-connected bed control hub — the hardware that pairs with the SleepIQ mobile app for firmness adjustment and sleep tracking. Coverage from Tom's Hardware and TechRadar documents a computer engineer's teardown of a Sleep Number bed's local hub over a UART/TTY connection, surfacing a possible console-access concern after the company pushed back on his self-built Homebridge integration for server-load reasons; the specific vulnerability mechanics were not independently confirmed beyond the search-result summary here. Two independent OUI blocks under one identifiable, product-documented, publicly traded company clears the bar for a substantive vendor entry rather than a bare single-OUI shell.

Registration date

Unknown/blank — IEEE's public OUI data (Registry, Assignment, Organization Name, Organization Address columns only) publishes no per-prefix assignment date; third-party "date registered" scrapes (e.g. maclookup.app) are database artifacts, not IEEE facts, and are not recorded as such

[Confirmed] — the IEEE MA-L registry (no date column present)

Security context

independent reporting (Tom's Hardware, TechRadar) covers a hobbyist's reverse-engineering of a Sleep Number bed's local hub, surfacing a possible console/backdoor access concern after the company pushed back on a third-party server integration; full technical mechanics unverified beyond the search-result summary [Likely] — https://www.tomshardware.com/tech-industry/cyber-security/engineer-hacks-his-sleep-number-bed-reveals-potential-backdoor-and-security-vulnerability, https://www.techradar.com/pro/security/unsurprisingly-smart-beds-are-pretty-easy-to-hack
