An IP address uniquely identifies your connection to the internet. These articles discuss what information that may or may not reveal about you or the person at the other end of an IP address, how much you can or cannot get, and who has the power to get it all.

When you cancel your Internet service, your IP address is released and made available to others. But, in reality, that may have already been happening.
The local host address is a quick way to fool browsers into connecting to software running on your local machine, instead of some remote software.
This IP address looks like both the IPv4 address and the IPv6 address that's been assigned to that particular network node.
It's no surprise that locations from IP addresses often come out wrong. In fact, Google has mapped us in a way that might surprise you.
