Java InetAddress Class Methods

Method

public static InetAddress getByName(String host) throws UnknownHostException//It returns the instance of InetAddress containing LocalHost IP and name.

public static InetAddress getLocalHost() throws UnknownHostException//It returns the instance of InetAdddress containing local host name and address.

public String getHostName()//It returns the host name of the IP address.

public String getHostAddress()//It returns the IP address in string format.

Example of Java InetAddress Class

Let's see a simple example of InetAddress class to get ip address of www.javatpoint.com website.

InetDemo.java

import java.io.*;  

import java.net.*;  

public class InetDemo{  

public static void main(String[] args){  

try{  

InetAddress ip=InetAddress.getByName("www.javatpoint.com");  

System.out.println("Host Name: "+ip.getHostName());  

System.out.println("IP Address: "+ip.getHostAddress());  

}catch(Exception e){System.out.println(e);}  

}  

}  

Host Name: www.javatpoint.com

IP Address: 172.67.196.82

Program to demonstrate methods of InetAddress class

InetDemo2.java

import java.net.Inet4Address;  

import java.util.Arrays;  

import java.net.InetAddress;  

public class InetDemo2  

{  

public static void main(String[] arg) throws Exception  

{  

InetAddress ip =  Inet4Address.getByName("www.javatpoint.com");  

InetAddress ip1[] = InetAddress.getAllByName("www.javatpoint.com");  

byte addr[]={72, 3, 2, 12};  

System.out.println("ip : "+ip);  

System.out.print("\nip1 : "+ip1);  

InetAddress ip2 =  InetAddress.getByAddress(addr);  

System.out.print("\nip2 : "+ip2);  

System.out.print("\nAddress : " +Arrays.toString(ip.getAddress()));  

System.out.print("\nHost Address : " +ip.getHostAddress());  

System.out.print("\nisAnyLocalAddress : " +ip.isAnyLocalAddress());  

System.out.print("\nisLinkLocalAddress : " +ip.isLinkLocalAddress());  

System.out.print("\nisLoopbackAddress : " +ip.isLoopbackAddress());

System.out.print("\nisMCNodeLocal : " +ip.isMCNodeLocal());  

System.out.print("\nisMCOrgLocal : " +ip.isMCOrgLocal());  

System.out.print("\nisMCSiteLocal : " +ip.isMCSiteLocal());  

System.out.print("\nisMulticastAddress : " +ip.isMulticastAddress());  

System.out.print("\nisSiteLocalAddress : " +ip.isSiteLocalAddress());  

System.out.print("\nhashCode : " +ip.hashCode());  

System.out.print("\n Is ip1 == ip2 : " +ip.equals(ip2));
