What you'll learn

  • Understand the format and need of IP address and subnet mask
  • Convert decimal to binary and binary to decimal
  • Determine the class of IP address
  • Determine the type of subnet mask (default or subnetted)
  • Calculate number of network, host, and subnet bits
  • Calculate number of subnets
  • Calculate number of hosts per subnet
  • Calculate network number (network id), broadcast address, first usable address, and last usable address
  • Create subnets based on given requirements
  • Design network addressing plan using VLSM

Course content

3 sections • 13 lectures • 1h 22m total length

  • IP Addresses1:42

    Explore IPv4 addressing: 32-bit addresses divided into four octets of eight bits, expressed in dotted decimal notation like 192.168.1.1, and learn how to convert between decimal and binary.

  • Binary to Decimal and Decimal to Binary Conversion3:09
  • IP Address Classes2:15
  • Sunbet Mask (Default and Subnetted)15:25

    Learn about IP addressing and subnetting, including class A, B, and C default masks and their prefix notation, and how to determine network, subnet, and host parts from binary counts.

  • Subnet Mask Format4:24

    Identify subnet mask format by ensuring all binary ones are on the left and zeros on the right, and validate masks through binary-decimal conversions and example analyses.

  • Exercise6:49

    Practice solving subnetting problems by interpreting classful addresses, calculating network and host portions from subnet masks, and applying prefix notation to verify results.

Requirements

  • Desire and devotion to learn the IP addressing and subnetting topic
  • Basic maths literacy
  • Basic computer literacy

Description

IP address and subnet mask are the keys to computer networking. You can unlock practical networking knowledge and skills only if you master this topic. In this course, I present concepts and calculations in an easy-to-understand manner.


How to master IP addressing and subnetting skill?

To take full benefit of this course learner needs to watch lecture videos multiple times and take notes. And solve the exercises without help.


How I presented this topic?

I divided IP addresses and subnetting topic into three sections. The first section covers the basic concepts and skills. It includes a number of exercises that make you ready to take the next sections confidently. The second section includes subnetting where we design and create the subnets for each class network and do a number of exercises. The third section includes variable length subnet mask, by reaching this topic you will be prepared to grasp the concepts quickly and easily. There I explained the need and benefit of VLSM, compared it with other addressing techniques, and included network address design exercises using VLSM.


This course includes:

  • Introduction to IP addresses

  • Binary to decimal conversion and decimal to binary conversion

  • IP address classes

  • Subnet Mask (default and sub-netted)

  • Subnet Mask Format

  • Addressing (default subnet mask)

  • Subnetting class C network

  • Subnetting class B network

  • Subnetting class A network

  • Variable Length Subnet Mask (VLSM)
