Key Features

MAC Address Lookup

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.

Vendor

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).

Lookup MAC Address

Yes! Use GET /v1/mac?mac=44:38:39:ff:ef:57 for programmatic access. Perfect for network inventory, security analysis, and device management.
