   Actually compared to other ISP they are a bit miserly. They only give you a   
   /60. My ISP gives me a /56 and many others issue a /48.

   I understand what you are saying, but that is IPv4 think. IPv4 adresses are a   
   scarce commodity, so naturally one does not want to be wasteful with IPv4   
   adresses. But waste is only an issue when there is a shortage. With IPv6 you   
   have to let go of that way of thinking. There is no shortage of IPv6 adresses.   
   So there is no reason for avarice. IPv6 was designed so that one can use   
   simple adressing schemes. The block size for a LAN subsegment is a /64. That   
   allows for SLAAC addressing based on 64 bit MAC addresses. Your ISP gives you   
   16 of those /64 blocks. So you can create 16 subnets. One for your hobby LAN,   
   one for your bussiness LAN, one for your guest LAN and one for your domotics   
   LAN. And 12 more.   
      
   It will take a while but eventually you will get used to the idea that IPv4   
   think does not apply to the IPv6 world. ;-)   
      
      
   Cheers, Michiel
