Hi, As a RIPE member we have our own IPv6 range (AS number of our internet supplier is used). Now we are trying to setup the routing. Our IPv4 range is divided in 3 subnets: 1 x /24 for sharedhosting, 1 x /25 for dedicated / co-located servers, 1 x /25 for a XEN cluster. The shared hosting subnet and the XEN cluster are 1:1 vlan's. The /25 for dedicated/co-located servers are divided in 2 x /27 and 1 x /26 Vlan's for customers. We want to do something similar for the IPv6 range. Our plan is: /64: Shared hosting 1 x Vlan: /96 (or smaller) /64: Dedicated / co-located servers 3 x Vlan: /96 (or smaller) /64: XEN cluster 1 x Vlan: /96 (or smaller) The reason for the /64 parts is that this way we can easily move parts of our servers to another DC if we want to. Does somebody see problems or better ways to do this? Thanks, Stefan
