Concept

What Is MAC Address to Binary?

A MAC (Media Access Control) address is a 48-bit unique hardware identifier for network adapters. This tool converts the 12 hexadecimal characters into their exact 48 binary bits.

Methodology

How Does It Work?

Strips separators (: or -). Converts each of the 6 byte pairs from hexadecimal into 8 binary bits (4 bits per hex character).

Formula & Rules

Mathematical Algorithm

\text{MAC}_{16} = 6 \times 8\text{-bit bytes} \xrightarrow{} 48\text{ binary bits}

Worked Problem

Step-by-Step Example

Convert 00:1A:2B:3C:4D:5E: 00 -> 00000000 1A -> 00011010 2B -> 00101011 3C -> 00111100 4D -> 01001101 5E -> 01011110.

Important Rules & Edge Cases

Standard MAC addresses have 48 bits (6 octets).
The first 3 octets represent the OUI (Organizationally Unique Identifier / Vendor).
