Depending on yoru mail program, you would look at the full email header which will tell you what IP address the mail was sent from.

As for Instant Messaging programs like Yahoo ... I'm not aware of a way.

Hi,
I realize there are many different ways to check someone's IP address. Is there any way to find out if someone else has been checking yours, looking it up in any way, or using it to look up info. in any way? Thanks.

No, not that I'm aware of.

hello. thanks for your insightful article. i'm doing some research on internet security & have some questions. is there a way for people ot get your ip from a website you visit (not someone who manages the site but someone else, especially for sites like online journals or thefacebook.com where people can read other people's accounts)? also is there a way, if someone knows your ip address, to use it to find other websites you visited, especially ones where you may have filled out personaly identifiable info? thank you

As you say, the site admins know all - for example I know the IP address from which you made that post. But barring stupidity on the server admin's part, the answer to your question is no, you cannot find the ip addresses of other site visitors. Now, stupidity would include making the server logs, which contain that information, visible somehow, or actually posting the IP on web pages. (Like, for example, if this comment form actually published the IP address from which each comment had come from. It does not, but it could.) Fortunately, in general, that's not the case, and your IP is not visible/accessible.

So the answer to the other question is also no... you cannot generally find out where people have visitted based on their IP address alone. It would require information from the servers, or information that was left on the PC that was used.

hey can some find my exact adress from my IP or can i find someone exact adress from an IP?

Only with the help of the ISP that is providing that IP address.

hello i have one question that is how can i read email headers of mails that r in my inbox is there any way to find out ip of anybody without reading email headers

How you view your email headers will depend on the email program you use. If they're not visible, most have some way to get at them.
