IP Subnetting Intro

Introduction

Understanding IP subnetting is a fundamental requirement for almost any techie - whether you’re a coder, a database administrator or the CTO. However, as simple as the concepts are, there is a general difficulty in understanding the topic.




Here we’ll break this topic into eight simple steps and help you put the pieces together to fully understand IP subnetting.




These steps will give you the basic information needed in order to configure routers or understand how IP addresses are broken down and how subnetting works. You'll also learn how to plan a basic home or small office network.




A basic understanding of how binary and decimal numbers work is required. In addition, these definitions and terms will get you started:
IP Address: A logical numeric address that is assigned to every single computer, printer, switch, router or any other device that is part of a TCP/IP-based network
Subnet: A separate and identifiable portion of an organization's network, typically arranged on one floor, building or geographical location
Subnet Mask: A 32-bit number used to differentiate the network component of an IP address by dividing the IP address into a network address and host address
Network Interface Card (NIC): A computer hardware component that allows a computer to connect to a network
