请问在win2000或nt中如何 （用c++ ) 动态地增加一个ip地址，且希望重启动机器后，此ip即无效。谢谢了。

利用IP Helper API。看下面的例子:

Module Name:

ipchange.cpp

Abstract:

This module illustrates how to programmatically change an IP address for
a specific network adapter on your machine. This program also demonstrates how
to retrieve existing network adapter IP configuration information.

IP configurations can be changed for a specific network adapter by using the
AddIpAddress() and DeleteIpAddress() Ip Helper APIs. These APIs require you to
understand adapter index numbers and IP context numbers. In Windows, every network
adapter has a unique index ID and every IP address has a unique context ID.
Adapter index IDs and IP context numbers can be retrieved using the GetAdaptersInfo()
IP Helper API. This program features a list option that displays current network
adapter configuration information by showing all adapters index numbers and IP
address context numbers associated with their corresponding network adaptors.

To execute this application, simply build the application using the Visual C++
Nmake.exe program generation facility. A ipchange.exe program should result.
Execute the ipchange.exe with the following parameters:

Ipchange.exe [ -l ] [ -a -n<index id> -i<ip address> -m<subnet mask> ]
[ -d -c<context id>]

-l List adapter index IDs and IP Address context ID information
-a Add IP Address option
-d Delete IP Address option
-i IP Address to specify with -a option
-m Subnet Mask to specify with -a option
-c IP context ID for an existing IP address
-n Index ID of an existing network adapter
