OpenDNS rolls out Conficker tracking, blocking
Found on The Register on Friday, 06 February 2009

A free service called OpenDNS is offering a new feature designed to alert administrators to the damage and help them contain it.
The service will also help network admins to quickly pinpoint any infected machines by checking their OpenDNS Dashboard. Starting Monday, any networks with PCs that try to connect to the Conficker addresses will be flagged on an admin's private statistics page. The service is available for free to both businesses and home users.
The idea itself is quite good. To bring down the botnet however, every PC would have to use OpenDNS, something which will not happen. But with the domain list available, even those ISPs who don't use OpenDNS have the chance to clean up their network abd alert infected users.
