hi,
i'm new to vb.net so if can anyone tell me how can i find out the IP address of the client who is trying to connect to the server. i'm thinking of authenticating the user based on the ip address, since the ip address is going to be static.
thanks,
sumit

Is this web based or an application...there are different ways to do it based on the type of app it is....NET provides several classes to handle this type of thing.

Well, you specified in an email that you needed to do this from a web application using vb.net, so you'll want to do something like the following...
CODE

using System.Web.HttpRequest

Dim client_ip as string

client_ip = Request.UserHostAddress()

There is also a .UserHostName() Method for the request object.

Hi, thanx for the quick reply...i'll get back to you if some problem comes...i'll try to break up the IP address n compare it with a range for its validity...if you have some good suggestion do mail me...because after getting the clients IP address i need to validate it with a range of IP address to allow him access to the website...

Thanx,
Sumit

Well, the best way to do that would be to split the string into an array, using the .Split() method with the '.' as the char delimiter. Then you'll have an array of 4 integers (although you'll have to convert from string to integer for each of the four). You can use one or all of those integers to compare to your decided ranges.

Sometimes host names resolve to more than one IP address. In that case, use this code-

CODE


Try
            'Declare new collection
            Dim IpCollection As New Collection

            'Retrieve IP address entries
            'To get a www address
            Dim i As Integer

            Dim ipE As Net.IPHostEntry = System.Net.Dns.GetHostEntry(-HOSTNAME-)
            Dim IpA() As Net.IPAddress = ipE.AddressList

            For i = 0 To IpA.GetUpperBound(0)
                'Add all to list
                IpCollection.Add(IpA(i).ToString)
            Next

            'Select the right address-

            Dim Ipaddress As String

            Ipaddress = IpCollection.GetValue(-Num-)

        Catch ex As Exception
            MsgBox("An error has occured")
        End Try



Replace -HOSTNAME- witht the host name (www.google.com, etc)

Replace -Num- with the number of the address. 0 returns the first address, 1 returns the second address, and so on...

you have to add Imports System.Net

Dim hostname As IPHostEntry = Dns.GetHostByName(hostname)
Dim ip As IPAddress() = hostname.AddressList
msgbox ip(0).ToString()
