Here the primary ISP CN Telecom does do DNS hijack, though I hate this.
anybody could try it using their DNS with nslookup:
> server 202.96.128.166
Default Server: cache-b.guangzhou.gd.cn
Address: 202.96.128.166
> www.notexists234256235.com
Server: cache-b.guangzhou.gd.cn
Address: 202.96.128.166
Non-authoritative answer:
Name: www.notexists234256235.com
Address: 59.37.71.85
www.notexists234256235.com doesn't exist, but this DNS does return an A RR.
Wah.
