  • Networks are using CIDR-Notiation for the network mask (e.g. /48)
As loopback address there is one address reserved, the very first (means all bits 0 except the last one):

A week later and my account had enough credits to request the subnet. I got a /48 network, or in otherwords, I have a network with 80 bits which I can use! This are more address then the whole IPv4 address space has! 😎

When you have the approval for the subnet SixXS did allready a lot of work for you: They sent you the actual address, and they make sure that this subnet is routed to your router address. So you only need to assign the addresses to your devices. Read more »
