    To use this values you have following options :

    1.)As label is your server side control you can easily access label text value in .cs file so main issue with javascript variable here you can assign this value to asp:hidden field so you can also access this in .cs file like :

    <script language=Javascript>
function setup_ip(json) {

$("#hdn").val('your javascript variable');
}
</script>
 <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true" ScriptMode="Release">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpnlHidden" runat="server">
    <ContentTemplate>
        <input runat="server" type="hidden" id="hdn" value="0" />
    </ContentTemplate>
</asp:UpdatePanel>

    cs file :

      string str = hdn.value//Where ever you want to store value

    2.)Another option you can use pagemethod here and pass both values as parameter to .cs file.

    javascript :

      PageMethods.getValue(parameter1,parameter2, OnSucceeded, OnFailed);
function OnSucceededID(result, methodName)
{
   //get result back if you want after successfully execution of pagemethod on server side  
}

 function OnFailedID(error, methodName) {
        if (error !== null) {
           alert(error.get_message());
        }
    }

    CS file :

       [WebMethod(enableSession: true)]
    public static returntype getValue(parameter type parameter1,parameter type parameter2)
    {
        do what you want to do with these values.

    }

    Hope it helps you.
