IP Address

Introduction

IP address. What is IP address? Is it just merely an address? Of course not. IP address is short for Internet Protocol (IP) address. It is an identifier for a computer or device on a TCP/IP network. It is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication.

The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.
