[cobalt-users] blocking Code Red attempts? RaQ3

["FantasticMoms.com" <admin@xxxxxxxxxxxxxxxxx>]

Hi guys,

I seem to be getting hit with Code Red Worm attacks quite a few times from
the same Ip address.  The address block virtually always begins with 66.51,
and seems to only be 4 or 5 different addresses.

Is there a way I can prevent this from reaching my server, as it is filling
up my log files with spurious entries.  I am hit with this thousands of
times per month.

I really don't want to block a whole section of the population though, so
what's the safest way of doing this?
