I do pretty much the same thing with Russia and China. Except for my
company offices over there.

Why not keep your threats to a minimum.......

I don't see why it would be inconceivable for NASA(or part thereof) to
block domain space for a country-whether or not that country had a
"thriving economy" or a "huge space program". Certain eastern European
countries have neither of these and I'm sure companies and organizations
often find themselves having to decide whether to take similar action
against them just as people have done against other countries at one
time or another.

Actually, he's (mostly) right. Back in 2000, the Jet Propulsion
Laboratory at NASA blocked all Brazilian traffic for several days due to
attacks:

Yeah, Im sure Nasa blocked all Brazillian domain space. With Brazils
thriving economy and huge space program I would see why Nasa would be of
interest.

Go back to the beach and your umbrella drink and stop spreading rumors.

Dan,

A few years ago, all Brazilian IP Address Blocks got blocked by NASA
(nasa.gov).

NASA claimed that they were getting to much hacking attempts and
defacements originating from Brazil.

One should be careful while blocking ip addresses blocks (sometimes full
A and B classes) because they may be blocking legitimate users too.

And you?re right, try to contact the abuse and s/cirt account!!

I will contact the abuse or s/cirt account the Net owner(whois).

90% of the time you will get a response. I normally do not include any

trace files or log snippets in the initial email.

They will ask for them if they plan to pursue.

Either way, I personnally think you should do all you can and 
especially DOCUMENT what you do in response to any successful or some 
unsuccessful attempts on your network.
