SSH login banner: IP address instead of DNS name

[Paul Hoffman]

Hi again. When I SSH into my 4.8 box, the first line of the banner is:

Last login: Mon Jun 30 19:31:44 2003 from 15-characters-of-a-host-name

That DNS name is truncated to 15 characters. I would much prefer an 
IP address. What do I need to change to get this?
