Block annoying 114so.cn DNS hijack
The answer is change the DNS to 188.8.131.52 and 184.108.40.206 which are provided by 114dns.com. Note that 114DNS is NOT 114so.cn
Every netizen in China may have experienced the problem that when visiting a nonexistent website, the browser jumps to a website named 114so.cn (or some other website running by ISP), which is full of annoying advertisement, to tell you that the website does not exist. And for the well-known reason, the public free DNS server provided by google 220.127.116.11 is blocked in China. 114DNS is a good alternative.
It doen't help to change the situation of being in the wall, but at least, it keeps some robbers out.
