Introduction IP Address JS

Validating IP addresses in JavaScript is often necessary in web development, particularly for client-side validation in forms and network configuration tools. JavaScript regex can be used to validate both IPv4 and IPv6 addresses.

IP Address Regex

The regex pattern for IP addresses in JavaScript checks for the correct format of IPv4 or IPv6 addresses.

The IP Address Regex Patterns

  • IPv4:

    /^(?:[0-9]{1,3}\\.){3}[0-9]{1,3}$/
  • IPv6: A more complex pattern due to the structure of IPv6 addresses.

How to Validate IP Addresses in JavaScript?

To validate IPv4 addresses in JavaScript:

function isValidIPv4(ip) {
    const ipv4Regex = /^(?:[0-9]{1,3}\.){3}[0-9]{1,3}$/;
    return ipv4Regex.test(ip);
}
console.log(isValidIPv4("192.168.1.1")); // true or false

Uses of IP Address Regex Validation

  1. Client-Side Form Validation: Ensuring users enter correctly formatted IP addresses on web interfaces.

  2. Network Application Development: Validating IP addresses in JavaScript-based network applications.

Conclusion

JavaScript's regex capabilities make it ideal for validating IP addresses in web environments. For comprehensive validation, including advanced IPv6 formats, Akto's regex validator offers a comprehensive solution.
