It's very sad to state that IPV4 are going to be exhausted very soon. RIPE.net has just started to use it's last /8.
Turbovp.com network is fully based on IPV4 so far but now we are going to start offering IPV6 in the coming future. We are getting our upstreams, routers, switches, servers and control panel ready to accept the IPV6 in our network.
