As far as reporting is concerned, we do have a number of ways you can
query our DShield data. First of all, by prefix (right now only /8, /16,
/24). But we do send out daily custom reports per request. Just send me
an e-mail.

There is also a test version of a report by ASN:
http://www.dshield.org/asreport.php
its experimental and feedback is welcome. It is setup to be machine
parsable.

It would be useful if these sites allowed you to query them with CIDR ranges to 
see if your site had originated any traffic that triggered their sensor arrays. The 
IDS community never seems to have wrapped its collective head around routing 
information. Looking up single IP addrs is just cosmetic. A real service would 
allow for concerned sites to check their entire address allocations. 

The solution we have takes a massive amount of data munging of a routing
table and is still experimental, but until attacks can be mapped to meaningful Internet
topographical information, the real value of these distributed IDS efforts cannot be fully 
exploited.  

I can forsee the argument that people shouldn't be able to look up other sites
which might be compromised, but if they are really so concerned, they should 
get their sites patched.

Devise a system that assumes owners of IP space WANT to know about problems.

and have a report sent to whoever needed to know about it.
