China hijacks Google's domain name - Computerworld

China hijacks Google's domain name
By Sumner Lemon, IDG News Service
SEPTEMBER 10, 2002
Users trying to access Google Inc.'s search
engine from inside China are finding
there's a good chance they'll instead be
sent to Tianwang Search, a search engine
operated by China's prestigious Peking
University.
Internet users are being sent to Tianwang
and other sites like it since Internet
service providers in China hijacked the
domain name of the Mountain View, Calif.,
Internet search company.
The frequency with which Chinese users have
been rerouted depends on the Internet
service provider (ISP) and the location
where the user is accessing the Internet.
That indicates traffic to Google isn't
being rerouted at a national level,
according to Duncan Clark, managing
director at telecommunication market
research company BDA China Ltd.
Domain names and Web addresses are matched
to IP addresses using Domain Name System (DNS) software. When an Internet user types
该网址不再展示 or any other address into a browser, a query is sent to the ISP's name server,
which returns an IP address for the site. ISPs in Beijing and Shanghai have apparently altered
those addresses, redirecting traffic to Chinese search sites, Clark said.
"It's not possible for someone else to do this," he said.
The Chinese government has sought to block access to undesirable Web sites using IP filters
since commercial Internet access first became available here in 1995. Search engines Google and
AltaVista Co. are the two latest Web sites to find themselves blocked in China. But this is the
first time censors have hijacked a domain name and rerouted traffic to another Web site, Clark
said.
China frequently clamps down on foreign media in the run-up to politically sensitive dates and
events. With Chinese President Jiang Zemin expected to hand power to a successor at the
upcoming Communist Party congress, Internet censors may be trying to tighten control over
information available on the Internet.
"It is in violation of the universal approach, changing the DNS system. When you type in a URL,
from anywhere in the world, you expect to get to that address," said Bruce Tonkin, chief
technology officer at Melbourne IT Ltd. and chairman of the Names Council of the Domain Name
Supporting Organization at the Internet Corporation for Assigned Names and Numbers (ICANN).
For Chinese users and Google alike, there may be little recourse available, however. "China has
not signed any agreement [not to tinker with the DNS system inside China]. No government has.
There is no legislation, no mechanism to stop them," Tonkin said.
