Are you sure that > the 'last' entries that are displayed as the actual hostname (as opposed > to the IP #) aren't in your /etc/host* files? Just a thought.. Not in my case. I don't have any /etc/host* files. last(1) doesn't resolve the names itself, it relies on what it reads from /var/log/wtmp. I'd guess that that's where the real decision gets made, but I'm not interested enough to look at it in more detail.
