How to get IP-Adess of the client (Windows autentication)

Hallo !

I am using IIS-Windows-Authentication in my intranet
(web.config <authenticati on mode="Windows" /> <identity
impersonate="tr ue" />

How can I get the users (client) IP-Address ?

I think the username can be read with user.identity.n ame.

Thanks

HttpContext.Cur rent.Request.Us erHostAddress

However, as has been mentioned countless times before, this is not 100%
reliable.

Hi Mark !

Your statement gives back 127.0.0.1.

This isn´t the IP of the client.

Any suggestions.

1) Create a new WebForm called debug.aspx

2) Drop the code at the end of this post into it, and deploy it on your web
server

3) Browse to it from a client machine

Thanks Mark !

Your script runs well. I can see many variables and value.

But what I need is the Windows-IP of the client. It isn´t shown.

Is this possible at all to get this value?

Nov 19 '05 #5
I need something like this:

Dim hostaddresses() As IPAddress
hostaddresses = Dns.GetHostByNa me(Dns.GetHostN ame).AddressLis t
Dim i As Integer
For i = 0 To hostaddresses.G etLength(0) - 1
Response.Write( hostaddresses(i ).ToString & "<br>")
Next

You've got pretty much all of the possibilities in that script.

When I run it locally, several of the variables contain my machine's
internal IP address i.e. 192.168.0.4

When I browse to it on my public website, they correctly show my cable
modem's external IP address.

I can only think that there's something on your network which is
interfering...

All, There are certain scripts that I have that only I want to run, both from home and sometimes work. If I add something like this (below) to the scripts, will this keep out unauthorized use (if the scripts are found somehow), or can the REMOTE_ADDR be easily spoofed ? Should I be checking HTTP_CLIENT_IP and HTTP_X_FORWARDED_FOR also ? $ip = $_SERVER; if (($ip == "x.x.x.x") or ($ip == "y.y.y.y"))

I am using a toolkit, part of which creates TCP/IP connections using a function 'Connect(<local IP>,<local Port>,<Remote IP>,<Remote Port>)'. This function's signiture looks very similar to the Socket object signiture. If you pass a blank local IP it will get the IP for the DEFAULT interface, which is not always the desired IP. How can I get the specific Local IP from a Remote IP? EX: Interface 1: 10.1.1.1
