What is a MAC Address?
A MAC (Media Access Control) address is a unique identifier assigned to network interface controllers (NICs) for use as a network address in communications within a network segment.
MAC addresses are used in the data link layer of the OSI model. They are most often assigned by the manufacturer of a NIC and are stored in its hardware.
Common MAC Address Formats:
- Colon-separated: AA:BB:CC:DD:EE:FF
- Hyphen-separated: AA-BB-CC-DD-EE-FF
- Dot notation: AABB.CCDD.EEFF
- No separator: AABBCCDDEEFF

Frequently Asked Questions
What is EUI-48?
EUI-48 (Extended Unique Identifier 48-bit) is the standard 48-bit MAC address format used in most network devices like Ethernet and Wi-Fi adapters.
What is EUI-64?
EUI-64 is a 64-bit identifier created by inserting FFFE in the middle of a 48-bit MAC address. It’s commonly used in IPv6 addressing.
What is bit-reversed format?
Bit-reversed format reverses the bit order within each byte of the MAC address. This is sometimes used in certain network protocols and hardware implementations.
How do I find my MAC address?
On Windows, open Command Prompt and type “ipconfig /all”. On Mac/Linux, open Terminal and type “ifconfig” or “ip link”. Look for “Physical Address” or “HWaddr”.
