It depends entirely on the site's admins. Usually, you don't want to do this, in case the IP changes. Plus, you run into a catch-22: if you use the IP without ever using the host name, you depend on the server responding with what you want in the absence of a host header (basically, you depend on the server running just one web site), but if that's the case, then concealing the host name is almost completely useless, because anyone else can talk to the same server without a host name. In fact, for big web sites, chances are the reverse DNS for that IP will at least point to a related domain, even if not to the exact web site you're accessing (for instance, www.wikipedia.org -> 198.35.26.96 -> text-lb.ulsfo.wikimedia.org). Basically, this either will stop you from accessing what you want, or won't conceal anything. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
