server, you need to enable recursion. - If your recursive DNS server has a public IP address, you MUST enable access control to limit queries to your legitimate users. Failing to do so will cause your server to become part of large scale DNS amplification attacks.

This evening, the vast majority of Google international websites, including Google.com, such as Google.com, Gmail, Google Reader, Google Docs, have been inaccessible in some provinces and cities in China.According to my analysis, the way to block Google is not new, is the use of Domain name hijacking (DNS hijacking) method, through technical means, Google's various types of foreign domain names resolved to a wrong address, making google.com inaccessible. Some time ago, CCTV had accused Google in
