how can I get to know the IP address when someone visits my site

I made search on google about how to get to know the IP address when someone contacts me .


It looks like there is one way that as someone visits the website you own, it's possible to get to know his IP address through the HTTP log. However, there is no details.

Would anyone tell me the details? Thanks so much

 

You can use a stats application that reads your web logs and provide this information such information in reports or graphs. SmarterTool offers a free version that would meet your needs.

Another option is to use Logparser to parse the web logs and gather this information. Once you install logparser on the server you could use the following example to provide a list of all unique visitors (IP addresses) that accessed the site.

logparser.exe "SELECT DISTINCT date, c-ip INTO c:\temp\visitors.txt FROM C:\WINDOWS\system32\LogFiles\W3SVC1\logfilename.log" -i:W3C -o:W3C

 

Super easy. Figure out what web server software you're running. Read the documentation to figure out where the log file is. Usually in a standard location, like /var/log/apache2/access.log. This is a plain text file, there's nothing complicated about it. In it you will see every request your server has served along with info like the browser (user agent), referer (the page they clicked through from, and yes it's spelled incorrectly in the HTTP spec), IP address, possibly resolved to hostname, and which page they were requesting along with an HTTP status code.

You can actually learn a lot from a simple HTTP request, if you are able to log things like request headers and use a bit of javascript to dig into browser details. This is what things like google analytics and facebook do to track users.
