"Mike West analyzed the part of the browser?s source code that
was responsible for making the connections. He discovered that
Chrome and Chromium are making those connections to help the
browser?s Omnibox figure out user intents correctly.
"The issue that Google aims to fix with these connections is
easily explained. Some Internet Service Providers have started to
intercept requests that do not resolve properly. If you enter
ghacks for instance in the address bar and tap on the return key
afterwards, Chrome needs to figure out if you want to search for
the term ghacks, or if you want to visit the site http://ghacks/.
Since it cannot do that, it displays an infobar if the word would
resolve to an existing domain name giving the user the chance to
open the domain with another click."
