Question

大家好我想获得eth0接口的ipv6地址，

例如我的eth0接口：

eth0 : Link encap:Ethernet HWaddr 11:11:11:11:11:11 inet addr:11.11.11.11 Bcast:11.11.11.255 Mask:255.255.255.0 inet6 addr: 1111:1111:1111:1111:1111:1111/64 Scope:Link

如何在java中获取inet6地址？

我无法正确使用InetAdress类。它总是返回一个ipv4地址。

感谢您的建议。我通过以下代码获得了有关接口的所有信息。

此外，InetAddress类在Linux中无法正常工作。（我尝试在linux中获取硬件地址）但是代码在Windows和Linux上运行正常。

import java.io.*;
import java.net.*;
import java.util.*;
import static java.lang.System.out;

public class GetInfo {

public static void main(String args[]) throws SocketException {
    Enumeration<NetworkInterface> nets = NetworkInterface.getNetworkInterfaces();
    for (NetworkInterface netint : Collections.list(nets))
        displayInterfaceInformation(netint);
}

static void displayInterfaceInformation(NetworkInterface netint) throws SocketException {
    out.printf("Display name: %s\n", netint.getDisplayName());
    out.printf("Name: %s\n", netint.getName());
    Enumeration<InetAddress> inetAddresses = netint.getInetAddresses();

    for (InetAddress inetAddress : Collections.list(inetAddresses)) {
        out.printf("InetAddress: %s\n", inetAddress);
    }

    out.printf("Up? %s\n", netint.isUp());
    out.printf("Loopback? %s\n", netint.isLoopback());
    out.printf("PointToPoint? %s\n", netint.isPointToPoint());
    out.printf("Supports multicast? %s\n", netint.supportsMulticast());
    out.printf("Virtual? %s\n", netint.isVirtual());
    out.printf("Hardware address: %s\n",
                Arrays.toString(netint.getHardwareAddress()));
    out.printf("MTU: %s\n", netint.getMTU());
    out.printf("\n");
 }
 }

问候。

您可以使用Inet6Address子类，请参阅http://docs.oracle.com/javase/6/docs/api/java/net/Inet6Address.html

Answer 3

private static String getIPAddress(boolean v6) throws SocketException {
    Enumeration<NetworkInterface> netInts = NetworkInterface.getNetworkInterfaces();
    for (NetworkInterface netInt : Collections.list(netInts)) {
        if (netInt.isUp() && !netInt.isLoopback()) {
            for (InetAddress inetAddress : Collections.list(netInt.getInetAddresses())) {

                if (inetAddress.isLoopbackAddress()
                     || inetAddress.isLinkLocalAddress()
                     || inetAddress.isMulticastAddress()) {
                    continue;
                }

                if (v6 && inetAddress instanceof Inet6Address) {
                    return inetAddress.getHostAddress();
                }

                if (!v6 && inetAddress instanceof InetAddress) {
                    return inetAddress.getHostAddress();
                }

            }
        }
    }
    return null;
}
