Look up MAC address vendor/manufacturer information and generate random MAC addresses
Accepted formats: AA:BB:CC:DD:EE:FF, AA-BB-CC-DD-EE-FF, AABB.CCDD.EEFF, AABBCCDDEEFF
The first 3 bytes (6 hex digits) of a MAC address identify the manufacturer. Here are some commonly seen OUI prefixes.

A MAC (Media Access Control) address is a unique identifier assigned to a network interface controller (NIC). It is used at the data link layer of a network segment and consists of 6 bytes (48 bits).
The first 3 bytes of a MAC address form the OUI, which identifies the manufacturer or vendor of the network device. OUIs are assigned by the IEEE Registration Authority.
MAC addresses can be written in several formats: colon-separated (AA:BB:CC:DD:EE:FF), hyphen-separated (AA-BB-CC-DD-EE-FF), dot-separated in groups of four (AABB.CCDD.EEFF), or as a plain string (AABBCCDDEEFF).
Modern devices often use MAC address randomization for privacy protection. This means the MAC address broadcast during Wi-Fi scanning may differ from the actual hardware address to prevent tracking.
