Express the following 48-bit binary MAC address in hexadecimal

Question

01010101 – 11011100 – 01110011 – 10101111 – 10011011 – 11100110

Answer 1

Hexadecimal numbers are formed with a 4-bit binary number. So an 8-bit binary number is broken up into two 4-bit binary numbers. The conversion from binary to decimal is as follows:

Binary Hex         Binary Hex

0000:    0             1000:    8

0001:    1             1001:    9

0010:    2             1010:    A

0011:    3             1011:    B

0100:    4             1100:    C

0101:    5             1101:    D

0110:    6             1110:    E

0111:    7             1111:    F

From the above table, we have

01010101 = 55

11011100 = DC

10101111 = AF

10011011 = 9B

11100110 = E6

So

01010101 – 11011100 – 01110011 – 10101111 – 10011011 – 11100110 Binary

is expressed as

55 – DC – AF – 9B – E6 Hexadecimal.
