No, when a local address of a connection is an IPv4-mapped IPv6
address, selecthost() does test it as a native IPv4 address.  So, we
need to lookup hostnames as an IPv4 in inithosts().  Please refer
selecthost() for detail.

I have no idea for now, but ftp(1) is a contrib software from NetBSD.
So, we need to discuss with the author of lukemftp.
