During the conversion to IPv6 there is a specific address range that has been allocated for use during specific migration conditions. This address range is for IPv4 Mapping. This IPv6 address allows an application that only knows IPv6 to be able to communicate with an application that only understands IPv4. This address range has the form of “::FFFF:{IPv4 address}”.
