SG MAC Address OUI Search
About the SG MAC Address lookup tool
The MAC Adderss OUI search helps identify unknown devices on your local network by simply typing their MAC address (or its OUI prefix), commonly listed by your NAT/Wireless router. It can be useful in identifying network adapter manufacturers, IoT devices, wireless clients, etc.
MAC address (media access control address) is a hardware identification number that uniquely identifies each device on a network, hard-coded by the manufacturer. It is typically a string of six sets of two-digits or hex characters, separated by colons, for example: 00:40:96:AA:BB:CC . The first three octets of a MAC address are referred to as the OUI (Organizationally Unique Identifier). The OUI uniquely identifies the manufacturer, vendor, or other orgranization that makes your networked device. OUIs are assigned to vendors by the IEEE.
