It is thorny thing. You may be right and I'm confused. I don't have much experience with IPv6. I just thought that any unicast IPv6 host, even IPv4-mapped IPv6 host, can communicate with any other unicast IPv6 host, including non-IPv4-mapped IPv6 host. Could you please suggest a good comprehensive article on the Web about IPv4-mapped IPv6 addresses and their usage? By the way, why you don't do the address type test in a daemon mode of ftpd? _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
