Explanation:
https://tools.ietf.org/html/rfc4291#section-2.2, #3:
An alternative form that is sometimes more convenient when dealing with a mixed environment of IPv4 and IPv6 nodes is x:x:x:x:x:x:d.d.d.d, where the ‘x’s are the hexadecimal values of the six high-order 16-bit pieces of the address, and the ‘d’s are the decimal values of the four low-order 8-bit pieces of the address (standard IPv4 representation).
Examples:
0:0:0:0:0:0:13.1.68.3 >>> compressed form: ::13.1.68.3
0:0:0:0:0:FFFF:129.144.52.38 >>> compressed form: ::FFFF:129.144.52.38
