1. Summary of Certification Process (part 1)

2. IPv6 Client IPv6 packets inside IPv4 packets

3. Test IPv6 Tunnel

4. Register a Domain Name Domain registrar –Registers whois info –Assigns authoritative DNS server –Puts “glue records” at the top-level domain (.info,.com, etc.) with A and AAAA records of your nameservers

5. Set DNS Records

6. Test DNS Resolution

7. IPv6 Web Server IPv6 packets inside IPv4 packets IIS Server Listening On [::]:80 HE.NET HTTP GET IPv6 Backbone Native IPv6 IPv6-to-IPv4 Gateway Native IPv6

8. IPv6 Email Server IPv6 packets inside IPv4 packets James Server Listening On [::]:25 HE.NET SMTP SEND IPv6 Backbone Native IPv6 IPv6-to-IPv4 Gateway Native IPv6

9. Chapter 3

10. 3.3 IPv6 Header Traffic Class: same as TOS in IPv4 Flow Label: used for QoS Next Header: can start a chain of headers

12. 3.4 IPv6 Extension Headers Extension headers are only examined by the destination node –Except for the rarely-used Hop-by-Hop Options header

14. Most Important Extension Headers TCP, UDP, ICMP6 –Specify the higher-layer protocol AH and ESP –Used for IPsec security Mobility –Used for Mobile IPv6

16. Routing Header Zero Deprecated, and recommended to be filtered out –http://www.ietf.org/rfc/rfc5095.txt A denial-of-service condition is possible by specifying a malicious path, such as a loop

17. ICMPv6

19. 3.5.3 Neighbor Discovery Main Uses –Autoconfiguration of IPv6 Addresses –Duplicate Address Detection (DAD) –Address Resolution (replacing ARP)

20. Router Advertisement Router Solicitation (RS) –Sent by an interface when it is enabled and needs an IP address Router Advertisement (RA) –Routers send these messages out, telling clients the network prefix and other configuration information

21. Neighbor Solicitation Neighbor Solicitation (NS) –A node sends this message to verify that a neighbor is still reachable, or for Duplicate Address Detection (DAD) Neighbor Advertisement (NA) –The response to a NS message

22. “Solicited Node Multicast Address” (see p. 3-27)

23. 3.5.4 Autoconfiguration Automatic addressing via two mechanisms –Stateless Autoconfiguration (SLAAC) No server needed Routers advertise network portion Hosts make up their own host portion –Stateful Autoconfiguration (DHCPv6) Requires a DHCP server

24. 3.5.6 Path Maximum Transmission Unit (PMTU) Discovery IPv4 allows each router to fragment packets if needed to pass into a network with a small MTU In IPv6, only the sender can change the packet size –This makes the process much more efficient

25. Path Maximum Transmission Unit (PMTU) Discovery ICMPv6 “Packet Too Big” messages are sent to inform the source device to use smaller packets
