Java网络编程从入门到精通（7）：用getAddress方法获得IP地址

package mynet;
import java.net.*;
public class MyIP
{
    public static void main(String[] args) throws Exception
    {
        InetAddress address = InetAddress.getByName("www.csdn.net");
        byte ip[] = address.getAddress();
        for (byte ipSegment : ip)
            System.out.print(ipSegment + " ");
        System.out.println("");
        for (byte ipSegment : ip)
        {
            int newIPSegment = (ipSegment < 0) ? 256 + ipSegment : ipSegment;
            System.out.print(newIPSegment + " ");
        }
    }
}
运行结果：
-45 100 26 122 
211 100 26 122
