Capturing IP addresses

For security reasons I need to know how to grab the IP address of each computer hitting a specific site. How would I get that info? Thanks

you will need to be a bit more specific, do you mean you want to create like an asp page and log every user who comes to this page and put there ip in a text file or something like that?.

or to do the same sort of thing but with a vb prog which monitors all ips connected to the computer to get the webpage? in which case you would need to either have the webserver running through your little app, and log every single ip address, or you would constantly need to call on the dos based netstat command and get a list of all the ip address's connected and if a new ip is found log it sort of thing?

or if you mean can you get the list of ip address's connected to someones server which you do not own, then you can't unless they log all the ip's in a text file and you gain access to this text file.

What I was looking for is to log the IP of each user typing an incorrect password in to our internal website. I have since found the answer. Thanks for the reply.
