According to RFC7296, section 3.15.1:
"The INTERNAL_IP6_ADDRESS is made up of two
fields: the first is a 16-octet IPv6 address, and the second is a
one-octet prefix-length as defined in [ADDRIPV6]."
In the code, the type is declared as FT_IPv4 and the field is decoded only if
it has 16 bytes. Instead, it should be declared as FT_IPv6 and the first 16
bytes should be added to the tree.
