To get a remote user's IP from Asp.Net, you can use Request.ServerVariables["REMOTE_ADDR"] or Request.UserHostAddress.

The Request object should be available anywhere in your ASPX page.

I don't think it's possible to reliably get the hostname through ServerVariables.

Assuming I understand what you're asking, System.Web.HttpContext.Current.Request will give your server-side code lots of information about the client making the request.
