How to get the IP address from the Domain Name in

Question

I am writing an application where I need the IP address. I have a domain name and I would like to know how to get the IP address from it. For example, "www.girionjava.com". How could I get the IP address of this website by programming in Java? Thanks.

Answer 1

InetAddress giriAddress = java.net.InetAddress.getByName("www.girionjava.com");

Then, if you want the IP as a String

String address = giriAddress.getHostAddress();

Answer 2

This should be simple.

InetAddress[] machines = InetAddress.getAllByName("yahoo.com");
for(InetAddress address : machines){
  System.out.println(address.getHostAddress());
}

Answer 3

(Extra mask in printing sine java considers all integers to be signed, but an IP address is unsigned)

InetAddress[] machines = InetAddress.getAllByName("yahoo.com");
for(InetAddress address : machines){
  byte[] ip = address.getAddress();
  for(byte b : ip){
    System.out.print(Integer.toString(((int)b)&0xFF)+".");
  }
  System.out.println();
}

Answer 4

InetAddress.getByName("www.girionjava.com")
