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

L

lvpaul

Hallo !

I am using IIS-Windows-Authentication in my intranet
(web.config <authentication mode="Windows" /> <identity
impersonate="true" />

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

I think the username can be read with user.identity.name.

Thanks

Click to expand...

HttpContext.Current.Request.UserHostAddress

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?

lvpaul

I need something like this:

Dim hostaddresses() As IPAddress
hostaddresses = Dns.GetHostByName(Dns.GetHostName).AddressList
Dim i As Integer
For i = 0 To hostaddresses.GetLength(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...
