The information on your computer should belong only to you, and in
order to maintain its privacy, you need to keep the IP address hidden,
so that all information will become unknown to all hackers as well as
web sites that track the number of your visits and collect information
every time. Therefore hiding IP address will disable such parties to
detect your identity and penetrate your privacy online because
information available to them is totally different from what you have
so no traceable evidence will be left behind.
