Question : How to block traffic from an ip on a Cisco ASA 5520

I want to block traffic from rzmr1.init.DE (195.43.53.25) and ns1.vpsville.ca (76.74.137.6) on my ASA5520. I keep getting event id 5504 onmy  DNS servers from these IPs. I know this is informational as a result of "Secure cache against pollution" but they are filling up my event viewer. Can these be blocked?

try...

Assuming that the acl_outside is on your outside interface (default).  Insert as the first two lines.

access-list acl_outside line 1 deny ip host 195.43.53.25 any
access-list acl_outside line 2 deny ip host 76.74.137.6 any
