Hi,

 How often does IP Fragmentation occur?
 Is it safe to restrict any fragmented packets to 'come' into my
 network?

Depends on your network and weather or not you care to be rfc compliant. 
I see real fragmented traffic all the time. I choose not to block it. Because 
it would break stuff that our customers need to use. So i just keep an eye on 
fragmentation and watch fro abuse of it. We host 125,000 web sites, and use 
iptables on our Firewalls (8).
