Your essential guide to deploying IPv6 on Windows® networks
Get in-depth technical information to put IPv6 technology to work—including networks with hardware running Windows 8 and Windows Server® 2012. Written by a networking expert, this reference explains IPv6 features and benefits, and provides detailed information to help you implement this protocol. You’ll learn best practices for using IPv6 services in your Windows network, whether you’re an IT professional, a network administrator, or an IT student.
Discover how to:
- Use Windows features and tools to implement IPv6 on your network
- Set up a test lab to experiment with IPv6 configuration and functionality
- Understand dynamic routing and the IPv6 routing protocols
- Use IPv6 transition technologies to support both IPv4 and IPv6 during deployment
- Implement IPv6 security features and measures
- Deploy native IPv6 connectivity to an IPv4-only intranet
- Apply best practices from the Microsoft corporate network case study
- Test your understanding of IPv6 concepts with end-of-chapter quizzes

following unicast addresses: ■ A link-local address for each interface ■ Additional unicast addresses for each interface (which could be one or multiple unique local or global addresses) ■ The loopback address (::1) for the loopback interface Typical IPv6 hosts are always logically multihomed because they always have at least two addresses with which they can receive packets—a link-local address for local link traffic and a routable unique local or global address. Additionally, each
prefix length. 4. In the next table entry, increment the value within the subnet bits. Convert the 16-digit binary number to hexadecimal, combine it with the 48-bit site prefix, and write the resulting subnetted address prefix. 5. Repeat step 4 until the table is complete.

Headers In comparing the IPv4 and IPv6 headers, you can see the following: ■ The number of fields has dropped from 12 (including options) in the IPv4 header to 8 in the IPv6 header. ■ The number of fields that must be processed by an intermediate router has dropped from 6 to 4, making the forwarding of normal IPv6 packets more efficient. ■ Seldom-used fields such as fields supporting fragmentation and options in the IPv4 header have been moved to extension headers in the IPv6 header. ■ The
