Decimal to Hexadecimal Conversion

Just like binary and octal, we will also use the same calculation technique.

 

Example 1:

 

67₁₀ = …….₁₆ ?

 

First of all 67/16 = 4, remainder 3

Then 4/16 = 0, remainder 4,

Thus the calculation result is 67₁₀ = 43₁₆

 

Example 2:

 

92₁₀ = ………………………₁₆ ?

 

First of all 92/16 = 5, remainder 12 (written C)

Then 5/16 = 0, remainder 5,

Thus the calculation result is 92₁₀ = 5C₁₆

Prefix Length

Prefix length is a simple method of representing the subnet mask, ie by counting the number of 1 bits (network bits) in the subnet mask and preceded with slash notation (/).
