📖 MAC Address Guide & Best Practices
🎯 Address Structure
Understanding the components of MAC addresses.
- 48-bit identifier divided into two parts
- First 24 bits: OUI (manufacturer)
- Last 24 bits: NIC specific identifier
- Least significant bit: U/L (Universal/Local)
- Second least significant bit: I/G (Individual/Group)
🔍 Address Analysis
