Introduction IP Address Java

In Java, validating IP addresses is a key task in network programming and data validation. Java's java.util.regex package can be used for regex-based IP address validation.

What is IP Address Regex?

Java regex patterns for IP addresses validate both IPv4 and IPv6 formats.

The IP Address Regex Patterns

  • IPv4:

    ^(?:[0-9]{1,3}\\.){3}[0-9]{1,3}$
  • IPv6: A complex pattern to accommodate the IPv6 format.

How to Validate IP Addresses in Java?

To perform IPv4 address validation in Java:

import java.util.regex.*;
public class IPAddressValidator {
    public static boolean isValidIPv4(String ip) {
        String regex = "^(?:[0-9]{1,3}\\.){3}[0-9]{1,3}$";
        Pattern pattern = Pattern.compile(regex);
        Matcher matcher = pattern.matcher(ip);
        return matcher.matches();
    }
    public static void main(String[] args) {
        String ip = "192.168.1.1";
        System.out.println("Is IPv4 address valid? " + isValidIPv4(ip));
    }
}

Uses of IP Address Regex Validation

  1. Network Management Software: Validating IP addresses in applications that manage network configurations.

  2. Data Integrity: Ensuring the correct format of IP addresses in databases and data processing.
