Internet Protocol Addressing Internet Protocol Addressing is the numerical labels found on device, such as computers and printers that use Internet Protocol for communication. This Internet Protocol Addressing serves in two roles. These roles are both host or network interface identification and location addressing. The common IP Addresses used today I found to be the IPv4 and IPv6, and can be static or dynamic. To differentiate the two, static IP addresses never change, while the dynamic is actually a temporary address that is assigned each time a computer or device accesses the Internet.
