Razer holds a single MA-L block registered as "Razer Inc", with a corporate dual-HQ in Singapore and Irvine, California. These OUIs appear on gaming laptops (the Blade line), gaming mice/keyboards/headsets, controllers, and the Sila gaming router. Razer is an active gaming-hardware brand that was taken private in 2022. A Razer OUI maps to the Razer brand, but an important classification nuance applies: many Razer peripherals connect via USB dongles and will not expose a network MAC at all, so a network-visible Razer MAC is most likely a Blade laptop's NIC or the Sila router rather than a mouse or keyboard. For triage, a Razer OUI maps to the Razer brand, but because most Razer peripherals are USB, a network-visible Razer MAC is most likely a Blade laptop or the Sila router.
