IP Addressing
So what’s a TCP/IP Address?
TCP/IP address works on the Network and Transport layer of the OSI-ISO reference model and Internet model. To understand IP addressing, Let’s take a look at the postal addresses. Every house or building must have its own postal address in order for mail to be delivered. An address consists of house number, street, and city. Every device such as (printers, routers, servers, gateways) needs a unique IP address to be identified in the network.
