How to use net Module (Node.js specific) In Javascript

Node.js provides the net module, which can be utilized to validate IP addresses as well.

Example:

JavaScript
const net = require('net');

function isValidIpAddress(ipAddress) {
    // For IPv4
    if (net.isIPv4(ipAddress)) {
        return true;
    }

    // For IPv6
    if (net.isIPv6(ipAddress)) {
        return true;
    }

    return false;
}

const ipAddress = "192.168.1.1";
console.log(isValidIpAddress(ipAddress));

How to check if a string is a valid IP address format in JavaScript ?

In this article, we will see how to check if a string is a valid IP address or not. An IP address is a unique identifier assigned to each device connected to a computer network that uses the Internet Protocol for communication. There are two common formats for IP addresses: IPv4 and IPv6. Checking if a string is a valid IP address format in JavaScript involves verifying if the string follows the rules for a standard IPv4 or IPv6 address.

These are the methods to check if a string is a valid IP address format in JavaScript:
