Convert unsigned 32-bit decimal to corresponding ipv4 address in JavaScript

Question

Consider the following ipv4 address -

128.32.10.1

If we convert it to binary, the equivalent is -

10000000.00100000.00001010.00000001

Additionally, if we convert this binary to unsigned 32-bit decimal, the decimal will be -

2149583361

Therefore, we can say that the ipv4 equivalent of 2149583361 is 128.32.10.1

We need to write a JavaScript function that accepts a 32-bit unsigned integer and returns its equivalent ipv4 address.

Example

The following is the code-

Real-time demonstration

const num = 2149583361;
const int32ToIp = (num) => {
   return (num >>> 24 & 0xFF) + '.' +
   (num >>> 16 & 0xFF) + '.' +
   (num >>> 8 & 0xFF) + '.' +
   (num & 0xFF);
};
console.log(int32ToIp(num));

Output

The following is the console output-

128.32.10.1
