Benchmark: IP to number performance

Script Preparation code:

function ip2num1(ip){
	var octets = ip.split('.').map(o=>+o);
	return (octets[3]) | (octets[2]<<8) | (octets[1]<<16) | (octets[0] << 24);
}

function ip2num2(ip){
	var octets = ip.split('.').map(o=>+o).reverse();
	var num = 0; var o;
	while(o = octets.pop()){
		num *= 256;
		num += o;
	}
	return num;
}

var testIps = Array(1000).fill(0).map(()=>Array(4).fill(0).map(n=>Math.floor(Math.random()*256).toString()).join('.'))

Tests:

Function 1
var result1 = testIps.map(ip2num1);
Function 2
var result1 = testIps.map(ip2num2);
