Testing for Understanding

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

  1. Why is the RFC 1886-defined DNS record for IPv6 name resolution named the "AAAA" record?
  2. What is the benefit to using the Windows .NET Server 2003 family DNS Server service over the Windows 2000 DNS Server service when manually configuring AAAA records?
  3. 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 Automatic Tunneling Pseudo-Interface that contains both a site-local prefix (FEC0:0:0:C140::/64) and a global prefix (3FFE:FFFF:A3:C140::/64). List the IPv6 addresses for the AAAA records registered with DNS by this host.
  4. Describe the importance of address selection rules for a node running both IPv4 and IPv6 that is using a DNS infrastructure containing both A and AAAA records.
