Denial of Service

[Nick Allum]

Just had a quick question, at the Bind Level, if there was a possible
Denial of Service coming from only a handful of ip address, would I be
able just to use an ACL to deny these or will my servers still be
flooded as it has to process the ACL?
Of what would be the quickest and easiest way to reduce the effect of
some type of Denial of Service where I am getting large quantaties of
requests from the same group of IPS.
 
 
Thanks
