I would venture to guess most users use ntpdate instead of ntpd so it  
would relookup every time.

I have two servers on gigabit setting and I have only gotten 2 spikes  
over the last 2 days. But it can go a day or two with solid spikes. I  
think the spikes I see are when larger isp's dns servers cache an  
entry with my ip in it, so all their customers keep getting my ip to  
use. (atleast how I explain it to myself)

patbox2 is for internal use only, just have it there as a base  
reference, patbox4 is set to to a low bandwidth, butlooks like I need  
to setup it's counting rules again.

patbox and patbox3 have been set to gigabit since they joined.
