/**
 * \brief          This function parses a CN string as an IP address.
 *
 * \param cn       The CN string to parse. CN string MUST be NUL-terminated.
 * \param dst      The target buffer to populate with the binary IP address.
 *                 The buffer MUST be 16 bytes to save IPv6, and should be
 *                 4-byte aligned if the result will be used as struct in_addr.
 *                 e.g. uint32_t dst[4]
 *
 * \note           \cn is parsed as an IPv6 address if string contains ':',
 *                 else \cn is parsed as an IPv4 address.
 *
 * \return         Length of binary IP address; num bytes written to target.
 * \return         \c 0 on failure to parse CN string as an IP address.
