Some mailers include an X-Originating-IP header, allowing a recipient to see the sender's IP address trivially. Gmail does not include that particular header. The headers it does include will simply lead back into the Google network.

More on the X-Originating-IP header, from 2001: http://www.wired.com/politics/law/news/2001/06/44567

As for whether or not Gmail reveals your IP address, it depends on who's asking. E.g., we have the recent example of LTC Paula Broadwell.

No, I've not send any emails. Court asked to give the email account's details (IP) and microsoft was happy to give.

Yeah, so Google is more than willing to do this too (and has, in the past).

It does not do it in Turkey.

Perhaps they are talking about the X-Originating-IP header? "Revealed" is a pretty loaded term, either way.

No, not X-Originating. Prosecutor asks to Microsoft to give all the details of xxx@hotmail.com. Microsoft sends all the informations of xxx@hotmail.com to the prosecutor. Google does not reply even.
