If you are accessing the Internet through a local network
you are using the IP of the one computer or router who's accessing the Internet.

The IP you have is only a local one,
if you download from others the IP which your ISP assigned to you is displayed on their client.

>Am I harder to identify?
Well that depends on where you using it.
If it is a school network with dozens of computers where many people use the same computer its hard to track you personally down. If someone tries to track you down he would track your school but he wouldnt know who used the computer..

but if you are using it from your home then its the same as
you are accessing the Gnet without a router.
