I am putting the finishing touches on a presentation I will be making =
later this week at the DNS-OARC meeting, but I also wanted to ask anyone =
here if they had data/ideas of items they are interested in seeing from =
the Open Resolver Project.

We perform a weekly scan of the IPv4 space looking for DNS servers that =
can be used in an amplification attack.=20

Some interesting data: about 46% of the IPs that respond to a DNS query =
do not respond from port 53, meaning they are "broken" in some =
interesting way.

I encourage folks to check your IP space here:

http://openresolverproject.org/

You can also e-mail the project to get direct access to per-ASN reports. =
 That email needs to come from a contact in the RIR object, or from a =
corporate address that can be easily identified as related to your org.

If you are an ISAC or similar, we can also assist you.

Thanks,
