They don't have an A record for nasa.gov. For those who don't have dig (or don't care enough to do an actual DNS request and would rather trust some other, lesser tool):
$ dig nasa.gov

Looks like the whole site is served through Akamai too.
What's a "direct @ url" ? Now we're overloading the @ for something else too?
