The issue of DNS amplification attacks has reared its ugly head
again in recent months, though the problem itself has been known for
several years.  Unfortunately the millions of open resolvers has
made it easy for miscreants to create large scale DDoS attacks using
a relatively small amount of resources, thus crippling their targets
with ease much like the smurf attacks of the past.

In an effort to try to help combat this problem, we'd like to make
available to the public a new FREE alerting service designed to help
pinpoint open resolvers in your address space.  In this manner, you
can in turn do your part to help clean up the open resolvers that
might fall within your purview.

The Million Resolvers Project, simply put, is a reporting system to
alert you when open resolvers are detected in your address space.

If you are interested, email us at info at cymru.com with a request
including the ASN(s) and/or netblock(s) that you're administratively
responsible for, to start the process of getting signed up for these
