To test your understanding of IPv6 name resolution, answer the following questions. See Appendix D to check your answers.
- Why is the RFC 1886-defined DNS record for IPv6 name resolution named the "AAAA" record?
- 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?
- 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.
- 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.
