I spent more than 10 minutes on this, start to now, so let's look at
those NASA records again.

;; ANSWER SECTION:
www.nasa.gov.           600     IN      CNAME   www.nasa.gov.speedera.net.
www.nasa.gov.speedera.net. 120  IN      A       208.254.75.142
www.nasa.gov.speedera.net. 120  IN      A       208.254.75.143

$ host 208.254.75.142
Host 142.75.254.208.in-addr.arpa not found: 3(NXDOMAIN)
$ host 208.254.75.143
Host 143.75.254.208.in-addr.arpa not found: 3(NXDOMAIN)

Two different hosts, neither with reverse DNS.

You have to consider how fast your target is moving as you take aim at
it. This particular one moves very fast. Resolving this once an hour
won't really do much for you. In general you've got the right idea,
though.


Now, that's interesting, never nocited here myself that sites like this might change so drmatically over such a small space of time, but I guess the costs of avoinding repeated DDOS attacks has made such things a reality of net-life.

Thanks for the info and research sir.
