As a phun side note. Reverse mapping government censorship of DNS. Since I think governments are starting to go down the slippery slope road of censorship here is how map out the censorship. If you have the list of the whole internet servers which answers on http port 80. Then you can reverse map government censorship dns list. Ie you can find out what the government wants to censor by doing lookups in the censored dns and for example opendns on the servers ip that answers on port 80, then you diff the results from the dns servers and if you get different answers you find out the government black list.
