MAC Address Lookup Tool

This tool allows you to quickly identify the manufacturer (vendor) of a network device using its MAC (Media Access Control) address. It’s designed for network administrators, IT technicians, and security professionals who need to verify hardware, track devices on a network, or audit their IT inventory.

The tool works with all valid MAC address formats, such as 00:1A:2B:3C:4D:5E or 00-1A-2B-3C-4D-5E.

How MAC Addresses Work

A MAC address is a unique identifier assigned to a network interface, like a Wi-Fi adapter or Ethernet card.

• MAC addresses are 48-bit numbers written in hexadecimal
• The first 24 bits (OUI – Organizationally Unique Identifier) represent the manufacturer
• The remaining 24 bits are unique to the device

This tool uses public OUI databases to identify the manufacturer associated with a MAC address.
