Changing you IP address?!!?!
Internal IP's don't get logged anywhere, only your external IP. So, generally internal IP's will look like 10.0.0.1-255 or 192.168.1.1-255 is the most popular, but those are only seen within your router in your home network. Otherwise what you see at cmyip or whatismyip.com is what is going to get logged without a VPN/Proxy.
