Converting an unsigned 32 bit decimal to corresponding ipv4 address in JavaScript
Problem
Consider the following ipv4 address −
128.32.10.1
If we convert it to binary, the equivalent will be −
10000000.00100000.00001010.00000001
And further if we convert this binary to unsigned 32 bit decimal, the decimal will be −
2149583361
Hence, we can say that the ipv4 equivalent of 2149583361 is 128.32.10.1
We are required to write a JavaScript function that takes in a 32-bit unsigned integer and returns its equivalent ipv4 address.
Example
Following is the code −
const num = 2149583361; const int32ToIp = (num) => { return (num >>> 24 & 0xFF) + '.' + (num >>> 16 & 0xFF) + '.' + (num >>> 8 & 0xFF) + '.' + (num & 0xFF); }; console.log(int32ToIp(num));
Output
Following is the console output −
128.32.10.1
