你要问的是不是以上三项在注册表中的位置,下面提供：
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces
项下有很多句柄你可以在里边找到不同的本地连接对应的句柄，在程序里进行修改就可以了,如果找不到，可以先在本地连接属性里修改tcp/ip协议的相应设置，然后到注册表里查找相应的数据就可以定位该位置了！源码这次就不给出了，就是修改注册表，和容易，您可以使用vb自带的函数，也可以使用wsh提供的脚本函数，当然也可以使用winAPI（比较复杂，要严格定义参数类型，即缓冲区，所以简单的修改不建议使用）。
希望您的问题能尽快解决！
建议你使用注册表的API进行修改
封装两个NET函数给你
private string GetReg(string RegPath) 取得注册表项内容
{
string str="";
RegistryKey hkml = Registry.LocalMachine;
RegistryKey software = hkml.OpenSubKey("SOFTWARE",true);
RegistryKey aimdir = software.OpenSubKey("krabs",true);
if (aimdir != null)
{
if (aimdir.GetValue(RegPath) != null)
str = aimdir.GetValue(RegPath).ToString();
if (str != null)
return str;
return null;
}
return null;
}
private bool SetReg(string RegPath,string Data) //设置注册表内容
{
RegistryKey reg = Registry.LocalMachine;
RegistryKey software = reg.OpenSubKey("SOFTWARE", true);
RegistryKey aimdir1 = software.CreateSubKey("krabs");
if (aimdir1 == null)
return false;
aimdir1.SetValue(RegPath, Data);
return true;
}
做exe程序获取本机IP地址用
System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName()).AddressList
做web程序获取客户端的IP地址用
HttpContext.Current.Request.ServerVariables（"REMOTE_ADDR"]）
