JDK1.4.2 不使用 getHostAddress 返回 IPV6 地址
JDK 1.5 以上可以正常返回 IPV6 地址。但JDK1.4.2仅返回IPV4地址。操作系统是Windows XP和Windows 7。有人设法在JDK 1.4.2上获取IPV6地址吗？
NetworkInterface iface = null;
for (Enumeration ifaces = NetworkInterface.getNetworkInterfaces(); ifaces
.hasMoreElements();) {
iface = (NetworkInterface) ifaces.nextElement();
InetAddress ia = null;
for (Enumeration ips = iface.getInetAddresses(); ips
.hasMoreElements();) {
ia = (InetAddress) ips.nextElement();
System.out.println(ia.getHostName());
}
}
我怀疑 java.net.InetAddressImplFactory 中有这个本机代码。
private static native boolean isIPv6Supported();
由于JDK1.4.2开发较早，可能与Windows中获取IPV6地址的原生库不兼容。这是正确的吗？
JDK 1.5 above returns the IPV6 addresses fine. But JDK1.4.2 returns only IPV4 addresses. The OS are Windows XP and Windows 7. Anyone manages to get the IPV6 addresses on JDK 1.4.2?
NetworkInterface iface = null;
for (Enumeration ifaces = NetworkInterface.getNetworkInterfaces(); ifaces
.hasMoreElements();) {
iface = (NetworkInterface) ifaces.nextElement();
InetAddress ia = null;
for (Enumeration ips = iface.getInetAddresses(); ips
.hasMoreElements();) {
ia = (InetAddress) ips.nextElement();
System.out.println(ia.getHostName());
}
}
I am suspicious that there is this native code in java.net.InetAddressImplFactory.
private static native boolean isIPv6Supported();
Since JDK1.4.2 was developed long time ago, it might not be compatible with the native library in Windows to get the IPV6 addresses. Is this correct?
