We can get the clients IP address using the Request object’s(The Request object retrieves the values that the client browser passed to the server during an HTTP request. ) property Request.ServerVariables Collection.
Request.ServerVariables Collection gets the values of predetermined environment variables.
“REMOTE_ADDR” gets the IP address of the remote host making the request.
string ipaddr;
ipaddr = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
here the string “ipaddr” stores the clients ip.

| AUTH_TYPE |
The authentication method that the server uses to validate users when they attempt to access a protected script. |
| CONTENT_LENGTH |
The length of the content as given by the client. |

| HTTP_<HeaderName> |
The value stored in the header HeaderName. Any header other than those
listed in this table must be prefixed by “HTTP_” in order for the
ServerVariables collection to retrieve its value.

HeaderName as dashes in the actual header. For example if you specify
HTTP_MY_HEADER, the server searches for a header sent as MY-HEADER.

The Windows NT® account that the user is logged into. |
| PATH_INFO |
Extra path information as given by the client. You can access scripts
by using their virtual path and the PATH_INFO server variable. If this
information comes from a URL it is decoded by the server before it is
passed to the CGI script. |
