Answer 1

No, it is not true. Changing your machine's IP address is not IP spoofing. IP spoofing is when you create network packets that have a source IP address that does not match the actual IP address of the source machine.

This could be achieved using RAW sockets or WinPCap using SharpPCap to interop to WinPCap http://www.tamirgal.com/blog/page/SharpPcap.aspx

Answer 2

Your machine IP address is simply the IP address given to your machine to be used internally by devices within your home network. This is how routers, switches and other client devices can deliver and exchange packets.

You cannot spoof your external-facing IP in this manner. Using proxies will make the proxy's IP appear to be your external-facing IP.

I do not suggest changing your internal IP unless you know what you are doing and actually have a need for it to be static. For example, I forward ports on my router so I can run services. The router knows to point that traffic directly to my internal IP. Because DHCP can change your IP (due to lease expiration and what not), it's best that I make my internal IP static.

Also, depending on your network configuration, your internal IP has a certain format, like 192.168.1.X.

The best way to change your ip address is through a proxy. In my search for a proxy, I found that having a reliable company behind the proxy is very important. Everything you do is sent through the company’s proxy, so you want to be sure that you can trust them to not read or steal your personal information. Or else there's no point in having a proxy.
