AW: IP assignment for virtual webhosting

Hi Nurani!

I think when *prohibiting* IP-based web hosting, some of us could run in
really bad trouble with SSL-based e-shops. 
I personally don't know a SSL-server which supports IP-less virtuals 
(LIRs out there - give me advice if you know one).


Are there statistics, which show how much addresses are wasted 
by IP-based (non SSL) web hosting?

> OUR SUGGESTION
> 
> The RIPE NCC has followed the deployment of HTTP 1.1 closely over the past

> webhosting and to change the current policy so that IP addresses can no
