 Refer to the earlier discussion about the “general-prefix”. We have `2001:DB8:6:C000::/60` as the IPv6 subnet created by 6rd. Taking this and appending `::1:0:0:0:0` results in the first subnet to be allocated to the network - the `FastEthernet0/0` interface there is automatically assigned `2001:DB8:6:C001::/64`, with the IPv6 address on the interface being `2001:DB8:6:C001::1/64`. Refer to the earlier discussion about the “general-prefix”.
