I think what happens here is the server to which you're connecting looks up the
hostname, given your ip address, and then it prints out the hostname. This is
common with ftp servers. Your hostname on the current machine may be totally

If dhcp server is providing a hostname, the dhcp client on your NetBSD machine

it has been set, if it's empty then dhcp server did not provide a valid hostname
