How to get client IP ?

[David Velazco]

Hello Everybody,

I try to use script to get client IP

<%
dim IPAddr
IPAddr = Request.ServerVariables("remote_addr")
Response.Write("Your IP Address is " & IPAddr)
%>

but script return IP of Web site, not CLIENT and not null value!

My site is hosted on W2003 server SP1, IIS, ISA

I'm only using ASP no ASP.NET

Regards,
David

Have the user enter it into a form field. ;-)

There is no guaranteed way to do it.

This is not true.

The IP of the user's own pc or router or proxy is shown.

This is the same question you, David, asked and I answered on:

Response.Write("Your IP Address is " & IPAddr)
IPAddr = Request.ServerVariables("remote_host")
Response.Write("Your IP Address is " & IPAddr)
%>

This is everything you will be able to retrieve from the server
variables if you run this script and cant find what your looking for
then its un ava to you for some reason.

Not if the web server is behind a ISA server, then it will show the ISA
server as the client

Why would you do that? Is hiding a server a usefull idea?

I suppose the OP would have to use another server as an intermediate, but I
would have to sleep on it getting a solution.

ISA is very useful if you are hosting many web sites on one IP for example.
you can send requests to the web site based on the domain name entered.

Yes you can do this by using hostheaders in IIS, but that causes other
problems like connecting with visual studio though FrontPage extensions for
example


depending on what David wants to know the clients ip for, maybe ISA can do
the job for him.
ISA gives a log of client ip's, it can also block certain ip's, but if he
needs it for his asp code, hen I don't have a answer

ummm, no

I can do that no problem and my colocated 2003 Server is using host
headers...

Try using the server admin with host headers

It all works fine for me, you just need to know what your doing.
