- Roku is registered to MAC prefix
AC:3A:7Aand 30 more in the IEEE OUI database. When a device's MAC address begins withAC:3A:7A, that block was registered by Roku — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note

About this vendor.
Roku holds about 31 IEEE blocks (MA-L plus one CID) registered as "Roku, Inc.", with blocks listing Saratoga, CA (12980 Saratoga Ave) and San Jose, CA (1155 Coleman Ave). These OUIs appear on streaming media players (boxes and sticks), Roku TVs (licensed to third parties such as TCL and Hisense), streaming dongles, and Roku-branded audio. Verified samples include AC:3A:7A, B0:A7:37, B8:3E:59, CC:6D:A0, D8:31:34, and DC:3A:5E (the oldest block is 00:0D:4B). A device-identification nuance for Roku TVs: Roku-branded streaming hardware uses Roku OUIs, but third-party Roku TVs (TCL/Hisense) may present either a Roku OUI (the embedded Roku streaming module) or the TV maker's own OUI, so this should be clarified per device/model. For triage, a Roku OUI is almost always a consumer streaming device, and in enterprise contexts it should be treated as shadow-IT/IoT.
