In this paper we show that the Internet web, from a user's perspective,
manifests robust scaling properties of the type 
,
where n is the size of the basin connected to a given point, P represents
the density of probability of finding n points downhill and 
s a
characteristic universal exponent. This scale-free structure is a result of
the spontaneous growth of the web, but is not necessarily the optimal one for
efficient transport. We introduce an appropriate figure of merit and suggest
that a planning of few big links, acting as information highways, may
noticeably increase the efficiency of the net without affecting its robustness.
