Module Overview
Configuring IPv4 Network Connectivity
Configuring IPv6 Network Connectivity
Implementing Automatic IP Address Allocation
Implementing Name Resolution•Troubleshooting Network Connectivity
Lesson 1: Configuring IPv4 Network Connectivity
What Is an IPv4 Address?
What Is a Subnet Mask?
What Is the Default Gateway?
What Are Public and Private IPv4 Addresses?•Demonstration: Configuring an IPv4 Address
What Is an IPv4 Address?
An IPv4 address identifies a computer to other computers on a network
IP Address192.168.1.201
IP Address192.168.1.202
IP Address192.168.1.200
Subnet 2
IP Address192.168.2.182
IP Address192.168.2.180
IP Address192.168.2.181
Subnet 1
What Is a Subnet Mask?
A subnet mask specifies which part of an IPv4 address is the network ID and which is the host
ID

192 168 1 0
Subnet maskxw y z

IP addressxw y z
192 168 1 200
What Is the Default Gateway?
A default gateway is a device, usually a router, on a TCP/IP internetwork that forwards IP packets to
other subnets

Subnet 1
Windows 8 clients
What Are Public and Private IPv4 Addresses?
Private• Nonroutable on the
Internet• Can be assigned
locally by organization
• Must be translated to access the Internet
Public • Required by devices
and hosts that connect directly to the Internet
• Must be unique• Routable on the
Internet• Must be assigned by
IANA
Demonstration: Configuring an IPv4 Address
In this demonstration, you will see how to configure a Windows 8 computer with:
• An IPv4 address
• A subnet mask
• A default gateway
Lesson 2: Configuring IPv6 Network Connectivity
Benefits of Implementing IPv6
Windows 8 Support for IPv6• IPv6 Addresses
Benefits of Implementing IPv6
Benefits of IPv6 include:
• Large address space• Hierarchical addressing and routing infrastructure• Stateless and Stateful address configuration• Required support for IPsec• Restored end-to-end communication • Prioritized delivery• New protocol for neighboring node interaction• Extensibility
Windows 8 Support for IPv6
IPv6 is Enabled by Default
• Windows 8 uses IPv6 by default to support security needs and additional features
Windows 8 Dual Stack
• Windows 8 facilitates the dual stack to use IPv4 and IPv6 simultaneously
Direct Access requires IPv6
• Windows 8 clients can use DirectAccess, which facilitates client computers connecting to the enterprise domain
Remote Desktop uses IPv6
• IPv6 supports Windows 8 File Sharing Security and Echo System features, such as Remote Access and DirectAccess
IPv6 Addresses
IPv6 Address Types• Unicast – use for one-to-one communication between hosts
• Multicast – use for one-to-many communication between computers that are defined as using the same multicast address
• Anycast – use for locating services or the nearest router
IPv6 Unicast Address Types• Global Unicast – globally routable and reachable
on the IPv6 portion of the Internet• Link-Local – use when communicating with
neighboring hosts on the same link• Unique Local Unicast – equivalent to IPv4 private
address spaces
Lesson 3: Implementing Automatic IP Address Allocation
Automatic IPv4 Configuration
Automatic IPv6 Configuration
Demonstration: Configuring a Computer to Obtain an IPv4 Configuration Automatically•Troubleshooting Client-Side IPv4 Autoconfiguration Issues
Automatic IPv4 Configuration
IPv4 Client
DHCP Server with
IPv4 Scope
IPv4 Router
IPv4 Static Configuration IPv4 Client
Automatic IPv6 Configuration
Automatic IPv6 Configuration Process
• DHCPv6 Server. Assigns Automatic IPv6 Configuration information to the client
• IPv6 Client. Uses DHCP-assigned IP Configuration to access network resources
• IPv6 Router. Provides a Gateway to the Internet or another Subnet
• IPv6 Static Client. Does not get automatic configuration from the DHCPv6 Server
Demonstration: Configuring a Computer to Obtain an IPv4 Configuration AutomaticallyIn this demonstration, you will see how to: • Automatically configure a Windows 8 computer
with an IPv4 address• Verify the IP configuration
Troubleshooting Client-Side IPv4 Autoconfiguration Issues
IPConfig is used to display IP configuration information and to release and renew
addresses
Option Description
/all Displays all IP address configuration information
/release Releases a dynamic IPv4 address lease
/renew Renews a dynamic IPv4 address lease

Lab Scenario
A. Datum Corporation is introducing new laptop computers for some of the managers in A. Datum Corporation. You need to test how the IPv4 configuration will behave when the managers are away from the office and a DHCP server is unavailable.
Lab Review
How are APIPA addresses for IPv4 similar to link-local addresses in IPv6?•How can you update a Windows 8 computer to use the correct information after a host record is updated in DNS, but the Windows 8 computer is still resolving the name to the previous IP address?
Types of Computer Names
Name Description
Host name
• Up to 255 characters in length• Can contain alphanumeric
characters, periods, and hyphens
• Part of FQDN
NetBIOS name
• Represents a single computer or group of computers
• 15 characters used for the name
• 16th character identifies service
• Flat namespace

Lab Scenario
An intern has been unsuccessful in attempts to resolve a network connectivity problem on a Windows 8 computer. The changes made to the computer have not been documented. You need to restore network connectivity for the computer.
Lab Review
