It just changed a week or two ago when I upgraded from 4.1.2 to 5.1.2 (probably cuz the upgrade took so long on my P200 :^)
before that I had the same IP for at least 8 or 10 months.
What config did you change??
Do I have to modify some config file somewhere??
This is what I get in the 'secure' log, and lots of it:
