IP Address in Networking :
Each
computer in a TCP/IP network must be given a unique identifier, or IP address.
This address, which
operates at Layer 3, allows one computer to locate another computer on a
network. All computers
also have a unique physical address, which is known as a MAC address. These are
assigned by
the manufacturer of the NIC.
MAC addresses operate at Layer 2 of the OSI model.An IP address (IPv4) is a 32-bit sequence of ones and zeros.To make the IP address easier to work with, it is usually written as four decimal numbers separated by periods. For example, an IP address of one computer is 192.168.1.2. Another computer might have the address 128.10.2.1. This is called the dotted decimal format.
