It's unclear to me whether you're saying the delay is in completing the
"last login" line (and showing the IP address) or the delay is after the IP
address is shown and before you get a shell prompt.  If it's the first of
these, it sounds like there's a DNS timeout trying to find the machine name
for that address and failing.  If it's the second of these, I would suspect
something in one of the profile or login files for the shell involved.
