Yes we are late but none of our customer needed/wanted ipv6 until now. So now we are considering our address planning for our infrastructure.
With IPV4 we use private addresses with small subnets between routers. With IPV6 we are considering using official unicast adresses and a /120 for each subnet. A packetfilter at the Border routers allowing only icmp echo/reply to the /56 containing this infrastructure subnets. What is best practice for a IPV6 addressing in a WISP network?
