OUI MAC Lookup


This tool supports the standard (IEEE 802) format MAC-48 addresses in the form of six groups of two hexadecimal digits, separated by hyphens (-) or colons (:), in canonical format (e.g. 01-23-45-67-89-ab or 01:23:45:67:89:ab ).

It also support the convention used by networking equipment such as Cisco, three groups of four hexadecimal digits separated by dots (.) (e.g. 0123.4567.89ab ). Again in canonical format, written in transmission bit order with the least significant bit transmitted first.

Examples:

  • 00-B0-D0
  • 00:0C:F1
  • 00-B0-D0-86-BB-F7
  • 00:0C:F1:56:98:AD
