As seen in dselect: *** Std net ftp 0.17-13 0.17-13 The FTP client
That's the FTP client from source package netkit-ftp, which does not support IPv6. You can invoke it with its real name "netkit-ftp".
Beware, the command "ftp" (/usr/bin/ftp) is often a symlink to some other real FTP client you may have installed. For instance, on my system, it invokes lukemftp, a more advanced FTP client which supports IPv6.
Mainstream wu-ftpd currently does not support IPv6.It could be that its refusal is generating errors that are being interpreted as name service errors but actually aren't.
I strongly doubt that. You would rather get an error message like "ftp: connect: Connection refused".
