= Why the Government of China is doing it =
Internet censorship in China is a known fact for very long. At least 18,000 websites are blocked from within mainland China, [60] including 12 out of the Top 100 Global Websites.
DNS spoofing allows the Chinese censors to do the following:
* Block access to specific sites.
* It can cause users with specific IP addresses or locations (i.e. neighbourhood, city, district) to connect to "fake" websites and intercept their user credentials. Imagine a fake Facebook or Gmail page which looks identical to the original one, but captures login credentials. With that information, the Chinese censors can access or read your private data, emails, contacts without you noticing.
* Block SSL certificate verification queries sent by the browsers (Online Certificate Status Protocol, OCSP).* Intercept emails.* Intercept messages sent by internet communicators.
* Attack websites by directing mass traffic from many Chinese users.
