Identify device manufacturers from MAC addresses
GET /v1/mac?mac=44:38:39:ff:ef:57
A MAC (Media Access Control) address is a unique identifier assigned to network interfaces. It's a 48-bit or 64-bit address typically displayed as six groups of two hexadecimal digits (e.g., 44:38:39:FF:EF:57).
We identify the vendor/manufacturer from the MAC address's OUI (Organizationally Unique Identifier - first 3 bytes), display the address type (EUI-48 or EUI-64), check if it's multicast, locally administered, or broadcast, and normalize it to standard format.
We accept MAC addresses with colons (44:38:39:FF:EF:57), hyphens (44-38-39-FF-EF-57), dots (4438.39FF.EF57), or no separators (443839FFEF57). Both uppercase and lowercase are supported.
