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

What Is an IPv4 Subnet?

Subnet 1172.16.20.0

Main Network172.16.16.0

Subnet 2172.16.24.0

172.16.20.12

Discussion: Selecting an Appropriate Addressing Scheme

Given the following scenario, how would you implement IPv4 addressing?

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

What is Name Resolution?

LLMNR4

Broadcast7DNS Resolver Cache2

Local Host Name1

Lmhosts File8

DNS Server3WINS Server6

NetBIOS Name Cache5

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

Name Resolution with WINSWINS 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

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

Configuring IPv4 Manually

Configuring IPv4 Automatically

Automatic private IP addressing (APIPA):

Is used if a DHCP server cannot be contactedü

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 Troubleshooting ToolsConsider using the following tools when troubleshooting IPv4:

• IPConfig.exe

• Ping.exe

• Tracert.exe

• Pathping.exe

• NSLookup.exe

• Event Viewer

• Windows Network Diagnostics

• Telnet.exe

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.

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?
