In my server logs I noticed continual requests for favicon.ico which is delivered as code 200 (OK).
I guess that this is a form of denial of service attack? To slow down the server, max out CPU, pollute stats etc.
Instead of an IP address in Apache Server logs I have something like: 65-121-129-148.dia.static.quest.net
But my firewall needs me to enter an IP address into a list of banned IPs.
Any tips on how to block this parasite?
