How to Use the MAC Address Generator
Our free MAC Address Generator allows network administrators, developers, and security testers to instantly create valid, randomly generated Media Access Control (MAC) addresses. It natively supports creating specific hardware addresses by assigning Organizationally Unique Identifiers (OUIs) for major tech vendors.
Step-by-Step Guide:
- Step 1: Choose Your Vendor. The first half of a MAC address (the OUI) dictates which company manufactured the network card. You can leave this as "Completely Random", or select a specific manufacturer like Apple or Cisco to generate a highly realistic spoofed address.
- Step 2: Choose Your Format. Different operating systems require different MAC formatting. Windows and Linux often use colons or hyphens, while Cisco networking equipment prefers dots. Choose the format that matches your testing environment.
- Step 3: Generate. Click the blue "Generate" button. A mathematically valid hexadecimal address will instantly appear.
- Step 4: Copy to Clipboard. Click the green copy button to save the address for use in your router settings, firewall rules, or code testing.
