IPv4 to int32

IPv4 to int32Codewars

Approach

solve the problem

1. split via '.' character

2. iterate process-1

   1. parse the value as a binary and padding 0

3. join process-2

4. parse process-3 as radix 10 integer

Solution

JavaScript

const ipToInt32 = (ip) => parseInt(
  ip.split('.')
    .map((v) => parseInt(v).toString(2).padStart(8, 0))
    .join(''),
  2
);
