Generate random, Cisco, Apple, or Raspberry Pi MAC addresses with bulk batch export.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Choose quantity (1 to 50) and separator style (colon, hyphen, Cisco dot, or raw).
Select Random OUI or vendor-specific prefixes like Apple, Cisco, or Raspberry Pi.
Copy the generated MAC addresses or download the bulk list as a .txt file.
An Organizationally Unique Identifier (OUI) is the first 3 octets (24 bits) of a MAC address that identifies the device manufacturer (e.g. Cisco, Apple, Intel).
Standard IEEE formats use colons (00:1A:2B:3C:4D:5E), Windows uses hyphens (00-1A-2B-3C-4D-5E), and Cisco switches use dotted quads (001a.2b3c.4d5e).
