Duration 3 days


Practical TCP/IP is a three-day course which provides you with the knowledge necessary to configure and troubleshoot IP based networks. You will start by learning the basics of communication then use this knowledge to discover how the TCP/IP protocol stack is formed. You will then set up routing before getting to grips with IP addressing including subnetting. You will then investigate naming schemes, what they are and how they can be used. TCP utilities and troubleshooting leads to a practical troubleshooting Lab. After a short discussion on how best to connect your network to the Internet you will finish with another practical session in which you will install typical network services (such as DHCP and DNS) and configure clients to make use of them.

Target Audience

The following will benefit from this course:

Network administrators responsible for the day to day troubleshooting and configuration of IP based networks
Network Managers seeking to understand the benefits and challenges of IP
Network Architects/designers charged with implementing/extending IP based networks
Those pursuing Microsoft Certification and requiring practical experience


You should have a working knowledge of computer based networks.

Course Content

Review of computer communication

This module reviews the background knowledge needed to appreciate the rest of the course

Major Topics

  • The communication process
  • MAC level communication
  • Ethernet Frames Logical systems
  • Protocol Stacks
  • Client-Server computing

Exercise: Basic networking

The DOD Four layer model

In this module you will discover how Internet Protocol stack is put together and how the individual layers interact. You will examine the major protocols used, their function and features

Major Topics

  • Protocol Stacks
  • Application Layer
  • Transport Layer
  • Ports & Sockets Internet Layer
  • Network Layer
  • Major Internet Protocols
  • The Microsoft Protocol Stack

Exercise: Matching function to Layer


In this module you will learn about IP routing. You will inspect Routing tables and discover what each entry means. You will be introduced to Routing Protocols and configure RIP

Major Topics

  • Single Segment Problems
  • Routers
  • How Routers Work: The Routing table Static Routers
  • Dynamic Routers
  • Configuration Issues

Lab: Examining & Modifying the Routing Table
Exercise: Designing a Routing Solution
Interactive: Configuring RIP routing and testing

IP Configuration

IP configuration is a major focus of TCP/IP. This module will teach you what an IP address really is and how it is divided. You will learn about address classes and how to modify them. Finally you will design and implement an IP system.

Major Topics

  • What is an IP Address?
  • Addressing Schemes
  • Dotted Decimal Notation Classful Addressing
  • Subnetting
  • Classless Inter-domain Routing (CIDR)
  • Supernetting

Exercise: Binary/DDN Conversion
Exercise: Identifying Classes
Exercise: Calculating Subnets & Masks
Lab: Design & configure a subnet solution on a multi-segmented network

Name Resolution

IP uses logical addressing to identify hosts but people prefer to use names. This module explains how a system gets from “” to “”. You will learn about the need for names, the schemes available, and implementation methods

Major Topics

  • Host methods
  • The DNS Name space & URL Convention NetBIOS methods
  • WINS, Broadcast, & LMHosts
  • Client configuration

Interactive: Client configuration
Interactive: Hostname resolution using HOSTS files
Interactive: NetBIOS resolution using LMHOSTS files

TCP/IP Diagnostic tools

In this session you will learn about the diagnostic tools available on TCP/IP systems, how to use them, and what part they play in troubleshooting. We then end with a troubleshooting lab

Major Topics

  • ARP
  • Ping
  • Ipconfig/Winipcfy
  • Tracert Netstat
  • NSLookup
  • Microsoft Specific tools

Interactive: Tools will be used when introduced
Lab: Troubleshooting connectivity problems

Internet overview

This module describes the techniques used to protect your corporate network from damage yet still allow access to the Internet

Major Topics

  • The three networks
  • The role of the DMZ
  • Firewalls NAT
  • Reverse Proxy

Installing & Configuring Network Services

In this session you will install, configure, and test the major services needed for efficient TCP/IP communications

Major Topics

  • DHCP

Exercise: Designing a segmented network using Microsoft TCP/IP
