Java API for InetAddress class has good methods for your needs, I see. Try these methods. You can check out other property getters of InetAddress for your further requirements.

public static void main ( String [] args ) throws UnknownHostException
{
    // Instantiate your own InetAddress object.
    InetAddress address = InetAddress.getLocalHost(); 
    String hostIP = address.getHostAddress() ;
    String hostName = address.getHostName();
    System.out.println( "IP: " + hostIP + "\n" + "Name: " + hostName);
}

This returns a forward slash. Use getHostAddress() instead. See http://stackoverflow.com/questions/12947435/inetaddress-tostring-returns-a-forward-slash – LeslieM Dec 05 '16 at 14:12
this will return hostname/ipaddress. – Gowtham Jul 23 '20 at 04:04

Just call the InetAddress toString() method. Also, if you specifically want the host name, use getHostName. If you want a string representation of the IP address, use getHostAddress().

sample :

InetAddress inet = InetAddress.getByName("193.125.22.1");
System.out.println(inet.toString());

for more information see: http://www.java2s.com/Code/JavaAPI/javax.net/InetAddressgetByNameStringname.htm

upvoted for the important bit : getHostAddress if you just want the address string – Todd Freed Sep 06 '14 at 18:36

What about

System.out.println(Inet4Address.getLocalHost().getHostAddress());

?
