How to Convert MAC Addresses
Different networking systems require MAC addresses to be formatted in different ways. A Cisco router will reject a Windows-formatted MAC address, and a Linux firewall will reject a Cisco-formatted address. This tool normalizes them for you instantly.
- Paste the MAC: Enter your MAC address into the text box. The tool is forgiving—you can paste it with colons (
:), hyphens (-), dots (.), spaces, or just raw text. - Convert: Click "Format MAC." The algorithm will strip away all invalid characters, extract the 12 true hexadecimal digits, and rebuild the address into every standard format.
- Analyze the Breakdown: At the bottom of the results, the tool splits the 48-bit address perfectly in half. The first 24 bits represent the OUI (the hardware manufacturer), and the last 24 bits represent the unique NIC ID of the specific chip.
