Request.ServerVariables("REMOTE_HOST") will always return whatever requested it's IP address ------------- Contribute to the working anarchy we fondly call the Internet |

Always? Try this one: http://m-200.ru/remote_addr/remote_addr.asp - http://m-200.ru/remote_addr/remote_addr.asp <% Response.Write("Request.ServerVariables("REMOTE_HOS T") :" & RH) |

While remote_addr can be used for ip spoofing, remote_host can be configured in the server to be a reverse-dns lookup. -------------

REMOTE_HOST in Dimitry's example link returns "m-200.ru" for me. It's a server configuration on his end. Your server is not set-up to return the reverse dns string, but quite a few are. If I cut and paste his code into a file on my server, it returns the ip. -------------

If server is not configured to return the reverse dns (you mean : \Inetpub\AdminScripts>cscript adsutil.vbs set /w3svc/EnableReverseDNS false Microsoft (R) Windows Script Host Version 5.6 Copyright (C) Microsoft Corporation 1996-2001. All rights reserved. EnableReverseDNS : (BOOLEAN) Flase ) It return "IP addres" on Request.ServerVariables("REMOTE_HOST") same as "REMOTE_ADDR" in my case server IPaddres if I set "EnableReverseDNS true" \Inetpub\AdminScripts>cscript adsutil.vbs set /w3svc/EnableReverseDNS true EnableReverseDNS : (BOOLEAN) True it return "m-200.ru" on Request.ServerVariables("REMOTE_HOST") Do you know other way to configure server to return the reverse dns? |

That's how it's done. Try running that script and set it to false. I'll re-run your asp link and see what's returned. Right now it returns: Request.ServerVariables("remote_addr") :195.42.92.165

Nothing was really wrong. You have the server option to return either the IP address or the Reverse DNS lookup for a REMOTE_HOST. Your server was originally returning the reverse DNS lookup. When Morningz ran the script on his server, he got the ip address because that's what his REMOTE_HOST option was. Most servers do return the ip address, but it's not required that they do so. The reverse dns lookup is also ok. -------------

| When you request a page (or any object that comes from the server using HTTP) your web browser sends your IP Address, so it is not from a cookie. Your IP is showing up as 192.168.0.4 because you are probably behind a router. JS cannot get the client IP but you can use ASP then validate the IP address. |
