Java Hostname Lookup
The following snippet shows how to get the hostname and IP address.
public static void main(String[] args) throws UnknownHostException {
java.net.InetAddress localMachine = java.net.InetAddress.getLocalHost();
System.out.println("Hostname of local machine: " + localMachine.getCanonicalHostName());
System.out.println("IP of local machine: " + localMachine.getHostAddress());
java.net.InetAddress localhost = java.net.InetAddress.getByName("localhost");
System.out.println("Hostname of localhost: " + localhost.getCanonicalHostName());
System.out.println("IP of localhost: " + localhost.getHostAddress());
}
Hostname of local machine: mail.theeggeadventure.com
IP of local machine: 67.207.137.114
Hostname of localhost: localhost
IP of localhost: 127.0.0.1
