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.
