Benchmark: IP Split vs Regex

Script Preparation code:

var value = "192.25.23.1"

Tests:

regex
// Check if value is an IP address if (/^(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/.test(value)) { return true; }
split
var parts = value.split("."); if (parts.length !== 4) { return false; } for (var i = 0; i < parts.length; i++) { var part = parseInt(parts[i]); if (isNaN(part) || part < 0 || part > 255) { return false; } } return true;
