[WEB4LIB] Re: IP Address Detection

Of course, this does not take into account multiple ranges.  That is why we were forced to use a database.

This may not be applicable to your situation, but with IIS and ASP, you can
get the visitor's IP address using:

Request.ServerVariables("REMOTE_ADDR")

To detect if the person is on campus, you might extract the first part of
the address:

strUserIP = (Left(Request.ServerVariables("REMOTE_ADDR"),8))
If (strUserIP = "134.197.") Then
    strUserLoc="OnCampus"
Else
    strUserLoc="OffCampus"
End If

In a Perl script, you could use:  $ip = "$ENV{REMOTE_ADDR}";

Hope this helps,
