How about something more along the lines of Linux's 'last -da'

The -a flag puts the host info in the last column and the -d flag
forces the OS to take the stored IP and re-look it up instead of
using the stored hostname info.  This would require that wtmp store
the IP as well as the hostname, which I'm not sure if NetBSD does.
