You can configure a Windows computer to use an ISATAP router in the following ways:

By using Group Policy as shown in Figure 6-15

By using the Set-NetIsatapConfigurationcmdlet

By using the Netsh interface isatap set router command

IMPORTANT
SCOPE OF ISATAP DEPLOYMENT
Do not deploy ISATAP across your entire IPv4 network infrastructure. Instead, enable it
only on select computers within your organization that need it.
Lessonsummary
■ Windows uses a dual IP layer TCP/IP stack that supports both IPv4 and IPv6
communications .

IPv6 is enabled by default and cannot be uninstalled, but you can selectively disable
different types of IPv6 interfaces and capabilities by editing the registry .

IPv6 addresses can be unicast, multicast, or anycast . Unicast addresses include global,
link-local, unique-local, special, and transition addresses .

The type of an IPv6 address can often be determined by its prefix.

IPv6 addresses can be assigned manually or by using stateless or stateful address
autoconfiguration.

Windows Server 2012 can be configured as a stateless or stateful DHCPv6 server.

Windows includes several IPv6 transition technologies, including ISATAP, 6to4, and
Teredo. Windows also includes several traffic-translation technologies, including
NAT64, DNS64, and PortProxy .

The components of an ISATAP deployment include ISATAP subnets, ISATAP hosts, and
ISATAP routers . Windows computers can be ISATAP hosts, and Windows Server 2012
can be configured as an ISATAP router.
Lesson review
Answer the following questions to test your knowledge of the information in this lesson . You
can find the answers to these questions and explanations of why each answer choice is co
ect
or inco
ect in the “Answers” section at the end of this chapter .
1.
Which of the following is not true about IPv6 on Windows Server 2012?
A.
Windows Server 2012 has a dual IP layer TCP/IP stack that supports both IPv4 and
IPv6 .
B.
IPv6 can be disabled on all interfaces by editing the registry on a Windows Serve
2012 computer .
C.
Windows Server 2012 can be used as a DHCPv6 server for stateless address
autoconfiguration.
D.
Windows Server 2012 can be used as an ISATAP router .

Network administration
2.
The IPv6 address assigned to an interface has a prefix identifier of FE80::/64. What type
of address is it?
A.
Global address
B.
Unique-local address
C.
Link-local address
D.
Multicast address
3.
Which Windows PowerShell cmdlet can be used to display the address information fo
an interface?
A.
Ipconfig
B.
Get-NetAdapte
C.
Get-NetIPAddress
D.
Get-NetIPInterface
4.
What do you need to do or use for Windows computers on an IPv4-only network to be
able to communicate with Windows computers on a different network that is IPv6-
capable?
A.
You need to do nothing because Windows computers automatically assign IPv6
addresses to their LAN interfaces using stateless address autoconfiguration.
B.
You need to deploy Windows Server 2012 as an ISATAP router and use it to
forward traffic between the IPv4-only and IPv6-capable networks.
C.
You need to deploy Windows Server 2012 as a Teredo server and use it to forward
traffic between the IPv4-only and IPv6-capable networks.
D.
You need to deploy Windows Server 2012 as a DHCPv6 server and use it to assign
global IPv6 addresses to the computers on the IPv4-only network .
Practice exercises
The goal of this section is to provide you with hands-on practice with the following:

Implementing DHCP failover using Windows PowerShell

Configuring a caching-only DNS server using Windows PowerShell
To perform the following exercises, you need at least two installations of Windows
Server 2012 that were deployed using the Server With A GUI installation option. The first
server should be the first domain controller in the forest root domain corp.contoso.com and
should have the DNS Server role installed and configured in the default manner using Active
Directory–integrated zones . The second server should be a member server in the contoso .
com domain and have no server roles installed . Both servers should have static IP addresses
assigned and have Internet connectivity . You should be logged on interactively to each serve
using a user account that is a member of the Domain Admins group .
