DDoS traffic

Hi All,

My appologies if this is against the group topic (and someone please let me know so I will not post again if I come to the same position)...

Is there a member of Comcast Abuse here...

For some time now a host has been attempting to DoS (as part of a larger DDoS) one of my machines. I have a reporting script that has now been running for at least 24 hours with no change in the traffic (even Kornet has clean up their reported hosts)...

Sample from a few minutes ago:
