Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

I'm using Chrome at Windows and with TCPView (of the SysInternals freeware suit) I see that chrome.exe establish connections to these IPs:

173.194.37.104
209.85.146.138

Using http://www.ipaddresslocation.org/ I check about these IPs and see they're related to Google.

Now, in order to clarify, these are the exact things I do:
Open up chrome, the default page is set to BLANK (i.e no homepage whatsoever).
Then I get into my website which has a blank page, so no "other" http requests are made.

Right from this point there is a persistent connection, usually to '173.194.37.104'.

What are these?? Very suspicious..

Edit #1:
- I'm in 'incognito' mode right from start, when launching Chrome, using a shortcut with the '-incognito' switch.
- I've turned off all phishing protections and other "advance" features in order to reduce Chrome's network activity.

What's perplexing is your other question about turning off security warnings for https traffic, but you're worried about connections to Google IPs from a Google product? I'm very confused. –  user3463 Dec 27 '10 at 21:27

You are aware, are you not, that Google Chrome was written by Google, and it connects to Google's servers even if you're not doing anything, in order to synchronise bookmarks, etc. with the mothership.

This is nothing to worry about. You have yourself identified the IP as belonging to Google. I recommend reading the small print in the licence agreement.

@Randolph thanks for the reply! As I've just added "Edit #1" you can read that I've turned off all "advance" features of Chrome and it's running on "private" browsing mode. As for your comment at the OP I can say that this is all done because the browser is being used in a private institution where we want no external "factors" whatsoever. –  Poni Dec 27 '10 at 21:34
    
As for reading the small print in the license agreement - could you point specifically? Because - THIS LOOKS LIKE A SPYWARE ACTIVITY. –  Poni Dec 27 '10 at 21:35

Poni, stop arguing. Randolph is really right! You have two options, to use Google stuff or not. In the first case, Google knows everything about you. Just an example: pcmag.com/article2/0,2817,2372498,00.asp –  Andrejs Cainikovs Dec 27 '10 at 22:14

@Andrejs you're missing the point - it's not an argue but a discussion. OBVIOUSLY I CAN SIMPLY STOP USING CHROME! If it's not clear then - I'd like to know what these "transparent" connections are and what information they send out. Then I'll be able to choose if I want to keep using Chrome or not. Kapish? –  Poni Dec 27 '10 at 22:28

Use packet sniffing software to see what information is being sent.

+1 Believe me I'm 1cm from firing up Wireshark and analayzing the data =) –  Poni Dec 27 '10 at 23:17

@Poni, why wait? Using Wireshark to see the host names that Chrome uses for those requests, you might even be able to add fake entries in your HOSTS file for those host names! –  Arjan Dec 27 '10 at 23:25

@ Poni, post back any interesting results. –  Moab Dec 28 '10 at 2:00

Have you tried to disable all Chrome Extensions? Especially extensions created by Google
(such as Gmail, Google Drive ...). For disabling them, read this article.
