The DNS64 and IVI prefixes must be those configured by the aft prefix-dns64 and aft prefix-ivi
commands.
With the DNS64 function, the AFT translates the IPv4 address resolved by the DNS server into an IPv6
address by using the DNS64 prefix specified in the 4to6 AFT policy for source address translation.
To configure a 4to6 AFT policy for destination IPv4 address translation, you must configure the ACL to
match the destination addresses of packets, but this requirement is not needed when you configure a
4to6 AFT policy for source IPv4 address translation.
For more information about ACL, see ACL and QoS Configuration Guide.
