Format & Normalize Hardware MAC Addresses
Clean and format MAC addresses into standard IEEE, Windows, Cisco, and hexadecimal notations.
About This Tool
MAC Address Formatter strips delimiters and normalizes MAC hardware addresses into IEEE colon, Windows hyphen, Cisco tri-dot, space, or raw hex representations with random MAC generation.
Key Features
Standard Colon format (00:1A:2B:3C:4D:5E)
Hyphen format (00-1A-2B-3C-4D-5E)
Cisco tri-dot format (001a.2b3c.4d5e)
Random locally administered MAC generator
How to Use This Tool
- Paste or type a 12-digit MAC address (with or without colons/dashes).
- Toggle Uppercase HEX if desired.
- Copy your preferred notation or click 'Generate Random MAC' for testing.
Why Use This Tool
- Standardizes disparate MAC address formats across network switches, DHCP servers, and documentation.
- Generates valid locally administered unicast MAC addresses.
Pro Tips
- Locally administered MAC addresses always have the second least-significant bit of the first byte set to 1
Frequently Asked Questions
What is Cisco tri-dot MAC notation?
Cisco switches and routers format 48-bit MAC addresses as three groups of four hexadecimal digits separated by dots (e.g. 001a.2b3c.4d5e).
