Course description

TCP/IP, or Transmission Control Protocol/Internet Protocol, is used to control how computer systems connect to the internet. And in this extensive course with one of our most experienced instructors, you’ll rediscover the world of TCP/IP. You’ll look at subnet masks, classful addressing, rogue DHCP servers, special IP addresses, Network Address Translation (NAT), Routing Information Protocol (RIP) and much, much more!

Course syllabus

Introduction to IP Addressing and BinaryDuration: 12:42

In this episode, Mike takes an in-depth look at how IP addresses are constructed.

Introduction to ARPDuration: 3:45

In this episode, Mike explores the address resolution protocol, which is used to resolve IP addresses.

Subnet MasksDuration: 12:11

In this episode, Mike introduces the concept of subnet masks, which are used to determine if a packet is coming from inside or outside a network.

Classful AddressingDuration: 10:23

In this episode, Mike explains the concept of classful addressing, which separates IP addresses into five classes.

Subnetting with CIDRDuration: 9:48

In this episode, Mike demonstrates how to subnet in binary.

More CIDR Subnetting PracticeDuration: 10:01

In this episode, Mike offers more instruction for subnetting.

Dynamic and Static IP AddressingDuration: 17:44

This episode examines the difference between assigning IP addresses manually and using DHCP to pass out addresses automatically.

Rogue DHCP ServersDuration: 6:29

In this episode, Mike shows how to check to make sure that your DHCP server is working, as well as how to check that you're not connecting to a rogue DHCP server.

Special IP AddressesDuration: 7:01

Learn about special IP addresses, which ones are reserved and what the 169.254.x.x address is.

IP Addressing ScenariosDuration: 14:46

Mike walks through some issues in IP addressing, including when everything should be working but connection issues are prevalent.

Introducing RoutersDuration: 15:18

In this episode, Mike explains how routers work to get packets from one network to another.

Understanding PortsDuration: 5:25

In this episode, Mike describes the purposes of well-known ports and ephemeral ports.

Network Address TranslationDuration: 6:24

Implementing NATDuration: 2:36

Mike demonstrates how to enable and configure NAT within a router.

Forwarding PortsDuration: 17:38

Learn about port forwarding, its usage, and how to create ranges and triggers to allow external devices to have internal communication.

Tour of a SOHO RouterDuration: 12:01

In this episode, Mike walks you through setting up a SOHO router. He's like a talking user's manual.

SOHO vs. EnterpriseDuration: 8:41

In this episode, learn the major differences between and SOHO and enterprise routers.

Static RoutesDuration: 12:39

Dynamic RoutingDuration: 10:35

Mike introduces you to routing concepts, such as metrics and latency. The episode also discusses types of routing protocols, such as distance vector and link state.

RIPDuration: 4:26

In this episode, Mike discusses the distance vector routing protocol called Routing Information Protocol.

OSPFDuration: 3:33

Continuing with the routing protocol discussion, Mike describes the most common IGP, OSPF.

BGPDuration: 5:39

Mike explains the Border Gateway Protocol.
