What I want to do is use one PC to test an application on another on the same 19.2.168.X.X
I would like to make it seem like SOAP requests are coming from a variety of different PCs, just to make the applciations log file easier to read and I have been told that virtual IP Addresses are the way to go. So, how do I defien a range and then use them one by one in VB? (I guss that this is effectively IP header spooging?)
Not exactly sure what you want to do but I'd suggest first looking at the WMI class Win32_NetworkAdapterConfiguration to see if you can do what you want with it.
If that class does not support it you might have to use INetCfg instead, where I think you can change pretty much any network settings, but it's a bit more difficult to use. Here's a codeproject article for using INetCfg from C# which might at least show you how to get started.
