获取用户真实IP问题

我使用下面程序查询用户真实IP,
String sip="";
String smac="";
sip = request.getHeader("x-forwarded-for");
if(sip == null || sip.length() == 0|| "unknown".equalsIgnoreCase(sip)) {
sip = request.getHeader("Proxy-Client-IP");
}
if(sip == null || sip.length() == 0 || "unknown".equalsIgnoreCase(sip)) {
sip = request.getHeader("WL-Proxy-Client-IP");
}
if(sip == null || sip.length() == 0 || "unknown".equalsIgnoreCase(sip)) {
sip = request.getRemoteAddr();
}
if(!"127.0.0.1".equals(sip)) //本机过滤掉
{
Process process = Runtime.getRuntime().exec("nbtstat -a " + sip);
InputStreamReader ir = new InputStreamReader(process.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
String line;
while ((line = input.readLine()) != null)
if (line.indexOf("MAC Address") > 0)
{
smac = line.substring(line.indexOf("-") - 2);
}
}
但是得到的IP一直都是127.0.0.1，这个是什么原因啊？

你是在本机上测试的吗~？~
