Course 6421B Module-1 Planning and Configuring IPv4

1. Module 1
Planning and
Configuring IPv4

2. Module Overview
• Planning an IPv4 Network Infrastructure
• Overview of Name Resolution Services in an IPv4 Network
Infrastructure
• Configuring and Troubleshooting IPv4

3. Lesson 1: Planning an IPv4 Network Infrastructure
• What Is an IPv4 Subnet?
• Plan an IPv4 Addressing Scheme
• Discussion: Selecting an Appropriate Addressing Scheme

4. What Is an IPv4 Subnet?
Subnet 1
172.16.20.0
Main Network
172.16.16.0
Subnet 2
172.16.24.0
172.16.20.12
172.16.16.31
172.16.24.27
172.16.16.7
Router
Router

5. Plan an IPv4 Addressing Scheme
172.16.16.0/22
172.16.20.0/22
172.16.24.0/22
172.16.16.1/20
172.16.28.0/22
172.16.17.0/24
172.16.18.0/24
172.16.17.254
172.16.17.1

6. Discussion: Selecting an Appropriate Addressing
Scheme
Given the following scenario,
how would you implement IPv4
addressing?
15 minutes

7. Lesson 2: Overview of Name Resolution Services
in an IPv4 Network Infrastructure
• What Is Name Resolution?
• Name Resolution with DNS
• Name Resolution with WINS

8. What is Name Resolution?
LLMNR4
Broadcast7DNS Resolver Cache2
Local Host Name1
Lmhosts File8
DNS Server3
WINS Server6
NetBIOS Name Cache5

9. Name Resolution with DNS
Workstation
207.46.230.219
Local DNS Server
What is the IP
address of
www.microsoft.com?
Root DNS Server
.com DNS Server
Microsoft.com
DNS Server

10. Name Resolution with WINS
WINS is required for the following reasons:
• Older versions of Microsoft operating systems rely on
WINS for name resolution
• Some applications, typically older applications, rely on
NetBIOS names
• When you need dynamic registration of single-label names
• If users rely on the Network Neighborhood or My Network
Places network browser features
• If you are not using Windows Server 2008 as your DNS
infrastructure

11. Lesson 3: Configuring and Troubleshooting IPv4
• Configuring IPv4 Manually
• Configuring IPv4 Automatically
• IPv4 Troubleshooting Tools
• The Troubleshooting Process
• What Is Network Monitor?
• Demonstration: How to Capture and Analyze Network
Traffic with Network Monitor

12. Configuring IPv4 Manually

13. Configuring IPv4 Automatically
Automatic private IP addressing (APIPA):
Is used if a DHCP server cannot be contacted
Assigns IP addresses on the 169.254.0.0/16
network
Cannot be used with:
• Active Directory
• Internet connectivity
• Multiple subnets
• DNS or WINS servers


IPv4 Client
DHCP Server with
IPv4 Scope and
IPv4 Site
Local Scope
IPv4 Router
IPv4 Static Configuration IPv4 Client

14. IPv4 Troubleshooting Tools
Consider using the following tools when troubleshooting
IPv4:
• IPConfig.exe
• Ping.exe
• Tracert.exe
• Pathping.exe
• NSLookup.exe
• Event Viewer
• Windows Network Diagnostics
• Telnet.exe

15. The Troubleshooting Process

16. What Is Network Monitor?

17. Demonstration: How to Capture and Analyze
Network Traffic Using Network Monitor
This demonstration shows how to:
• Capture traffic with Network Monitor
• Analyze the Captured Traffic
• Filter the Traffic
• Save the captured data

18. Lab: Planning and Configuring IPv4
• Exercise 1: Selecting an IPv4 Addressing scheme for
branch offices
• Exercise 2: Implementing and Verifying IPv4 in the branch
office

19. Lab Scenario
You are a network engineer for Contoso Ltd. You must
select a suitable IPv4 addressing scheme for a branch office
deployment and then implement elements of the scheme.
The branch will initially use manually assigned IPv4
addresses, although it is planned that they will implement
DHCP in the future.
Once you have determined the appropriate configuration,
you are required to configure the client workstations
according to your plan.

20. Lab Review
• In the lab, you used the graphical interface to configure
the IPv4 address on NYC-CL2. What else could you have
used?
• What syntax would you have used to achieve this?
