Hey,

I would just use cp_ip6_address() to parse the hex representation (which is
a legal spelling of that address), then extract the IPv4 address using the
bool IP6Address::ip4_address(IPAddress &) function, then print the
IPAddress in the usual way (with IPAddress::unparse() or operator
<<(StringAccum&, IPAddress)).
