IP Addresses
An IP address (Internet Protocol address) is a unique address that devices use in order to identify and communicate with each other on a computer network utilizing the Internet Protocol standard (IP)—in simpler terms, a computer address. Any participating network device; including routers, computers, controllers, time-servers, printers, Internet fax machines, and some telephones—can have their own unique address. An IP address can uniquely identify a specific computer or other network device on a network. IP addresses are managed and created by the Internet Assigned Numbers Authority. IANA generally assigns super-blocks to Regional Internet Registries, who in turn allocate smaller blocks to Internet service providers and enterprises. Computrols' website IP address is 72.32.2.230. You can type that into your address bar and it will bring you to Computrols.com. IP addresses are part of the Network Layer in the OSI model.
