Request for off line security help

Request for off line security helpI can assure you that the reply you got
back was totally accurate.
Why?
Because I work at the company in question, and send out many
responses to inquiries like yours.

This is the technology we use to deliver content faster than everyone
else.
You probably went to one of our customers websites and that is why

you would have gotten the initial port scan.

  Aloha all,

  My box was recently scanned by someone. I sent a note to the NOC that
owned the IP address and got a curious reply back. To sum up, they are
systematically scanning folks as part of "network intelligence." Stated
reason is to, "optimize performance when your customers access the web
resources of our customers." This guy further goes on to say, "Our network
was pinging your system because it appeared to be a name
  server with a sufficient number of resolution requests for our customer
web sites to be placed on the list of network nodes to be constantly
observed for Internet congestion."

  I don't know if I believe this just yet, especially since my system is
just a home computer and port 53 is fire-walled closed... It would be one
thing if the port scan were a cursory check to see where my system was, but
it also appears that the port scan checked for a whole bunch of stuff. Now,
I am not a security whiz... If anyone has a few minutes and would volunteer
to review the log extracts and e-mail I would be happy to share it. I don't
want to make the discussion "too public" until some one can help me figure
out if the proposed answer from the scanning NOC is believable. Once I know
that, I'll be happy to share my experience in order to "alert the public" so
to speak.

  Thanks in advance,

  Ben
