Yes, it was on a higher order of magnitude. We probed 7,477,875 networks
in the course of a couple weeks. For simplicity's sake, and because the
``packet monkeys'' don't know any better, we only probed the /24 blocks,
sending pings to the .0 and .255 of the /24. For the next `round' we will
be allowing other CIDRs to be probed, and will be adding other features,
including seaches by AS number, and searches by netblock. We did not
release this information (or the entire list) immediatly, trying to give
the admins time to fix their networks, before the kiddies had a chance to
get at it.
Real-time probes are another feature we are looking into, but cannot be
implimented at our current hosted location.
I thank you all for your time and support of the project. We have received
a multitude of emails from people thanking us for the site, and telling us
of their network fixes.
