About MAC formats

  • Colon (AA:BB:CC:DD:EE:FF) — Unix, Linux, macOS convention.
  • Hyphen (AA-BB-CC-DD-EE-FF) — Windows / IEEE-canonical convention.
  • Cisco (AABB.CCDD.EEFF) — three dot-separated 16-bit groups.
  • Bare (AABBCCDDEEFF) — no separators; useful for config files and Wake-on-LAN payloads.
