Explanation:
Section Reference: Defining the Dual IP Stack
IPv4-mapped addresses have the first 80 bits set to 0 (note the double colon), the next 16 set to 1 (shown as
ffff), and the last 32 bits populated by the IPv4 address. These addresses look like IPv6 addresses, other than
the last 32 bits, which are written in the customary dot-decimal notation. For example, ::ffff:192.0.2.128
represents the IPv4 address 192.0.2.128.
