How to get the IP of Server and client?

[ad]

Hi,
I am use VS2005 to develop Web application.
How can I get the server's and client's IP with program?

 

[Guest]

Try to use this:
to get HOST IP use Request.ServerVariables["LOCAL_ADDR"]
to get client IP use Request.UserHostAddress

to get client IP use Request.UserHostAddress

This can't be relied upon, due to firewalls, proxies, IP spoofing etc...

Mark,

Under that argument, nothing can be relied upon that is sent from the
client . As far as stats go (and as I work with them) getting the
request IP is the closest to obtaining the user's IP. Unless there is a
better way?

That's pretty much the case - quite a few browsers have an "impersonate"
option where they can "appear" to be something else entirely...

As far as stats go (and as I work with them) getting the request IP is the
closest to obtaining the user's IP.

So long as you trust your users not to spoof it...

Unless there is a better way?

There isn't...

Have a look at the properties of my earlier reply - you can see from my
IP address that I'm in the UK, etc...

Have a look at the properties of this reply - where do you think I am
now?

You simply cannot rely on the IP address reported to your server...
