Retrieve IP address from User

[evaleah]

I am trying to retrieve an IP address for my users when they commit certain transactions. The code I was using before I updateded to Framework 1.1 and VS 2003 was:

Dim sIP As String
Dim oAddr As Object

With GetHostByName(GetHostName())
oAddr = New System.Net.IPAddress(.AddressList(0).Address)
sIP = oAddr.ToString
End With

Now I am getting an error that says the .AddressList(0).Address piece is obselete.

I also tried Request.UserHostAdress but this returned the OS address and not the broadcasted one.

I looked at the documentation on this and for some reason cannot make heads or tails of what should replace the address list. It looks to me like it is still appropriate. Anyone have any ideas about how this should be now?

Thanks!

The REMOTE_ADDR and REMOTE_HOST server variables will give you the users IP.

I know I am probably just being thick, but could you give me an example bit of code of how to use those?

Thanks!

simply by:
Request("REMOTE_HOST") or Request("REMOTE_ADDR")

Whose IP address are you trying to log? The web server or the client?

The client.

[coolbiz]

Page.Request.UserHostName or Page.Request.UserHostAddress

I think
Page.Request.UserHostAddress and
Request("REMOTE_ADDR")
give the same result, i.e. client machine's IP.

Isn't it??

[coolbiz]

It is but Request("REMOTE_ADDR") is there for the backward compatibility purpose. It is recommended to use the .NET built-in properties and routines (counterparts) instead.

Thanks...

Thanks for the suggestion CoolBiz. However, I have already tried that and it is not returning the correct value. Please see the quote below from my original message.

Originally posted by evaleah I also tried Request.UserHostAdress but this returned the OS address and not the broadcasted one.

There may, of course, be some other piece I am missing. If so, please let me know. But setting sIP = Page.Request.UserHostAddress returned 127.0.0.1 and not the broadcasted IP address of the user.

Thanks again!

The only way you can get 127.0.0.1 (this is also known as the loopback IP or localhost IP) from the client is if you're browsing the page on the same machine where your webserver is.
If that is the case, and you actually want to get the LAN IP, make sure you do not use http://localhost/....../somepage.aspx but instead http://hostname/..../somepage.aspx.

Thank you Cool Bizs. Can we say 'DOH'.

Of course I was testing it on the same PC as I was hosting the site. What was I thinking?

When I accessed the page via the hostname it worked. Thanks for the heads up.
