Do you know exactly what an IP address is?

An IP address (or Internet Protocol address) is, in fact, an unique address that devices, such as computers, use in order to identify and talk to each other on a computer network, by using the Internet Protocol standard. In easier terms, a computer address. Any participating device of a network - including devices such as routers, computers, time-servers, Internet fax machines, printers and even some telephones - can, and often do, have their own unique address. An IP address can be viewed as the equivalent of a street address or as a phone number for a computer, or some other network device found on a network. (courtesy of WikiPedia).
