You can find some documents by googling with `IPv4-mapped IPv6 address'. In addition, you should read RFC 4038: http://www.ietf.org/rfc/rfc4038.txt?number=4038 rosti> By the way, why you don't do the address type test in a rosti> daemon mode of ftpd? Because, ftpd(8) in daemon mode doesn't accept an IPv4 using an IPv4-mapped IPv6 address by issuing the IPV6_V6ONLY socket option. Please refer socksetup(). In inetd mode, enable/disable use of an IPv4-mapped IPv6 address is depending on how to configure inetd.conf. So, we need to pay attention to an IPv4-mapped IPv6 address in inetd mode.
