Your IP address is a unique identifier, kind of like a mailing address, associated with your online activity. Any time that you use the internet (shopping online, sending emails, streaming TV), you’re requesting access to a specific online destination, and in return, information is sent back to you. How does that work? Well the IP stands for Internet Protocol, which lays out the standards and rules (yes, otherwise known as the protocol) for routing data and connecting to the internet. This protocol is a set of rules each party needs to follow to allow for a bi-directional flow of data.
