DDOS Bot Blacklist

Subject: DDOS Bot Blacklist
Date: Sun, 14 Nov 2004 22:26:48 -0000
Hi,
I was wondering if anyone had looked into the creation of a blacklist for
DDOS bots?  
There are obvious concerns; firstly, where the source may be spoofed, though
most of the Attack Mitigation Systems should deal with stateless attacks and
secondly, with so many of the bots originating from DHCP scopes, many bots
this could be overcome by rapid aging of the addresses or only including
addresses used more than once indicating a long term address lease in the
scope.
