Network requirements
As shown in Figure 92, Host C is in an IPv4 network and has an IPv4 address of 4.4.4.2 and a domain
name of hostc.com. Host A is in an IPv6 network and has an IPv6 address of 6::2. The DNS server is in
the IPv4 network and has an address of 3.3.3.5. The DNS server has the mapping between hostc.com
and 4.4.4.2.
Host A wishes to visit Host C through domain name hostc.com.

Configuration consideration
To meet the requirements, perform the following configurations:
• On Router B, enable AFT, and configure a DNS64 prefix and a 6to4 AFT policy because the
address of Host A is not an IVI address.
• On Host A, specify the IPv6 address 2000:0:303:305:: of the DNS server (which is translated from
IPv4 address 3.3.3.5 by using the DNS64 prefix).
