You can get the IP address of the client using the
HttpRequest.UserHostAddressproperty (an instance can be accessed usingthis.Requestfrom any page or using static propertyHttpContext.Current).As far as I know, there is no standard method that would compare the IP address with a specified range, so you’ll need to implement this bit yourself.
You’ll probably want to check this for every request, which can be done either in the
OnInitmethod of every page (that you want to block) or in theBeginRequestevent of the application (typically inGlobal.asax).If you detect a blocked address, you can output an empty (placeholder) page using
Server.Transfermethod (Response.Endwould be another alternative, but that simply cuts the page – returning an empty page, whileServer.Transferallows you to output some message to the client).
