MAC Address Vendor Lookup
Enter a full 48-bit MAC address or the first 6 to 12 hexadecimal characters of a vendor assignment. The lookup accepts compact, colon-separated, hyphen-separated, and space-separated input.
Randomized and Private MAC Addresses
Many phones, tablets, laptops, and smart devices can use randomized or private MAC addresses on Wi-Fi networks. These addresses usually set the locally administered bit, which means the address was chosen by the device or operating system instead of assigned directly from an IEEE manufacturer prefix.
When a randomized MAC address is used, the vendor lookup may return no manufacturer even though the device is working normally. In that case, use router client names, DHCP history, device settings, or the device's non-private hardware MAC address for identification.
About MAC Address Prefixes
MAC address prefixes are assigned through IEEE registries such as MA-L, MA-M, and MA-S. A full device MAC address may include extra device-specific characters after the assigned vendor prefix, so full MAC address pages point search engines to the matched manufacturer prefix.
