Testing for Understanding

To test your understanding of IPv6 address autoconfiguration, answer the following questions. See Appendix D to check your answers.

1. List and describe the states of an IPv6 autoconfigured address.
2. What is the formula for calculating the amount of time an autoconfigured address remains in the deprecated state?
3. How does a router obtain addresses other than link-local addresses?
4. According to RFC 2462, what addresses are autoconfigured for LAN interfaces on hosts when duplicate address detection for the EUI-64-derived link-local address fails? What is the behavior for the IPv6 protocol for the Windows .NET Server 2003 family and Windows XP?
5. A host computer is running Windows .NET Standard Server and is assigned the IPv4 address 172.30.90.65 on its single LAN interface. IPv6 on this computer starts up and receives a Router Advertisement message on its LAN interface that contains both a site-local prefix (FEC0:0:0:29D8::/64) and a global prefix (3FFE:FFFF:A3:29D8::/64). List and describe the autoconfigured addresses for all interfaces on this host.
