Question

What is the 32-bit Hexadecimal equivalent of the IP address 223.1.3.27?

Answer 1

32-bit IP addressing is the IP address scheme used in Internet Protocol 4.

To convert into hexadecimal equivalent, convert each section of 8 bits of data into hexadecimal and then join together, where every 2 characters (padded if required) will determine each section.

Process of conversion of decimal to hexadecimal - Repeatedly divide the number by 16 until it becomes zero and then take the remainder in opposite direction in a sequence.

Note - if remainder is greater than 9, map it to letters from a to f (a = 10, b = 11, ....)

For 223,

Operation	Quotient	Remainder
223 / 16	13	15 ( f )
13 / 16	0	13 ( d )

(223)10 = (df)16

For 1,

1 / 16 = 0, 1

(1)10 = (1)16

For 3,

3 / 16 = 0, 3

(3)10 = (3)16

For 27,

Operation	Quotient	Remainder
27 / 16	1	11 ( b )
1 / 16	0	1

(27)10 = (1b)16

Combining all the conversions -

Hex equivalent = df.1.3.1b

Removing dots and padding for 2 symbols each,

Hex equivalent = df01031b
